PET bottle plastic bottle controversy renewed antimony containing carcinogens

Recently, plastic bottles storm breaks out, said bottle PET ( polyester ) materials contain carcinogenic heavy metals antimony, many of whom are well-known brands , such as Coca-Cola, Niulanshan Erguotou , Fortune cooking oil and so on. The bottle HDPE ( high-density polyester ) and PP ( polypropylene ) material is not detected antimony .However , China Beverage Industry Association wrote that the detection method they used was not specified in the national standard method , while the published data did not identify the unit , not a scientific, not as a basis to determine whether the product is qualified . China Beverage Industry Association also pointed out that plastic food packaging containers used in the production of antimony catalyst production process has been widely used and recognized around the world , including China 's .For now, antimony remains in a plastic bottle in is real , but the antimony residues harmful to health if inconclusive , research institutions have also divergent views, this plasticizer incident just happened last time when liquor quite similar . According to the reporter , PET packaging its previous liquor plasticizer storm also broke clear plastic box the high temperatures will precipitate plasticizing agent . Studies have shown that , PET can heat to 70 , but the use of more than 10 months, it may be released DEHP and other plasticizers, plasticizers heating possibility undoubtedly also contribute to precipitation . In other words , antimony affected by factors such clear plastic box packaging as temperature and beverages nature , will slowly move to the costumes, drink bottles go .Antimony can irritate the eyes, nose , throat and skin , continuous exposure can damage the heart and liver function, inhalation of high levels of antimony and antimony can cause poisoning symptoms include vomiting, headaches, breathing difficulties , severe cases may die. While inhaling too much antimony contracted lung cancer cases has yet to appear, but not rule out the potential danger to the human body.September 2002 in accordance with the provisions of the World Health Organization , and the date of the antimony content in water intake should be less packaging boxes wholesale than 0.86 mg / kg per day . Japan limited PET bottle antimony content should be less than 200ppm, used for hot filling drinks , disable PET bottles containing antimony . EU regulations, the antimony content in food should be less than 20ppb, environmentally friendly PET fiber grade antimony content of not more than 260ppm.Experts, high temperature , acidic ( alkaline ) drinks, long term storage, these are the factors that promote the transfer of antimony from the packaging to the beverage . If the dress is acidic blister packs packaging substances, antimony easier to accelerate precipitation . To stay away plastic packaging box from " Antimony " harm , drink as much as possible PET packaging acidic ( alkaline ) beverages, while paying attention to choose from close to the production date , good storage conditions of the product . It should be noted , do not re-use PET bottle material is best not to install hot water, buy PET packaging after long-term storage and clam shells for sale do not drink , should be consumed as soon as possible .Technological processes and the overall management of the domestic beverage packaging companies are behind the rapid development of the food packaging industry , increased competition, raise standards , raw material price increases, profit making companies drastically reduced malpractice exposure management under external pressure. The scale of China 's beverage packaging business is uneven, the lack of effective monitoring of production quality , disorderly market competition significantly , leading to a continued decline in the profits of the entire industry .At present , the domestic beverage packaging business to import Japanese and Korean production equipment mainly due to the limitation of domestic machinery clamshell boxes investment scale and technical level , only at the secondary position , the majority of SMEs as the main target . Production environment is equally bleak , except for a twenty -renowned enterprises have built GMP workshop and waste water , waste gas treatment facilities outside most of the production workshop supporting imperfect .

PET plastic bottles containing carcinogens drink acidic beverages PET packaging

Recently, clear plastic box there are well-known plastic packaging box online media for Coca-Cola, Lee Kum Kee and other 12 brands of beverages and condiments plastic bottles were tested, the results showed that one of the nine PET ( polyester ) material bottle was found to contain carcinogenic heavy metals antimony, the remaining 3 PP ( polypropylene ) and HDPE ( high density polyethylene ) bottle material is not detected antimony .After detecting announced March 8 , China Beverage Industry Association responded that the detection method Sohu Health Channel UN [ microblogging ] home authority is not the method used by the national standards required , the data did not identify the unit simultaneously released without scientific, can not serve as a basis to determine whether the product is qualified .Experts advise: drink acidic beverages PET packagingYesterday , clamshell boxes an associate professor in charge of the detection of Clothing Technology Materials Science YAN Gong said in PET plastic material up to antimony residues , as in the synthesis of PET , antimony is commonly used catalysts. Thirty or forty years ago, we introduce Japanese technology , has been used up to now , but the extensive use of antimony harm is great, antimony can precipitate to beverages , especially acidic beverages such as cola easily dissolved heavy metals." In the test , we found that higher levels of antimony relatively inexpensive plastic bottles of branded products , of which blister packs packaging there may be a regeneration, the regeneration of secondary issues . Currently antimony content standards for beverage bottle is certainly not strictly , follow or the 1991 standard . " YAN Gong said," with the antimony catalyst for the production of PET material clear plastic box packaging as plastic bottles , effective and relatively inexpensive , since we disclose the results came out , the industry indeed have some impact , but the environmental point of view, we call on businesses should packaging boxes wholesale be made to improve technically and to reduce the use of antimony oxide as a catalyst , use titanium catalyst synthesis of PET. "According to reports, a carcinogenic effect of trivalent antimony , high temperature, acidic ( alkaline ) drinks, long term storage, these are favorable factors to promote the transfer of antimony from the packaging to the beverage . If the dress is acidic substances, antimony easier to accelerate precipitation . To stay away from " Antimony " harm , drink as much as possible PET packaging acidic ( alkaline ) beverages, while paying attention to choose from close to the production date , good storage conditions of the product .Dong Jinshi, food safety experts say , in the case of existing standards lag , qualified necessarily safe , consumers should keep your eyes open to see the fine print , note promising material bottles , PET material as buying less bottled drinks .In addition, YAN Gong introduced , recycling waste PET plastic bottles into the textile industry has more than 10 years , with six bottles of Coke will be able to do a chemical fiber garments .Antimony (Sb): toxic irritantAntimony atomic number 51 in the periodic table , is A metal element. Element symbol Sb. Silver-white lustrous metal hard and brittle . Toxic , the minimum lethal dose ( rats , intraperitoneal ) 100mg/kg. Irritation. Legend of Ancient Western had a lot of people trying to take stibnite clam shells for sale containing antimony to treat leprosy , the results of disease progression, one died .According to reports, antimony for human health depends on the cumulative amount is exceeded , and smoking , as it is harmful to long for people to figure out. Plastic bottles and clothing are daily contact with people , even if the product standard , the long run can not rule out the potential risks of antimony on the human body .When selecting PET plastic bottles, should be avoided as much as possible to buy PET packaging acidic foods ; while paying attention to select from the production date near, storage conditions are good products.

Functional packaging film to improve the packaging effect increase the added value

Is the thickness of the plastic film 0.25mm ( i.e. 250m) or less smooth and soft plastics , according to different purposes blister packs packaging , can be divided into packaging films , agricultural films, industrial films , medical film. Among them, functional packaging film developed rapidly in recent years , and more and more industry attention.Functional differences also called packaging film packaging film , means the film has no special features of the conventional film . Introduction of special features to make the effect of significantly improved packaging film , added value improved significantly , development and application of functional plastic packaging films are often able to get the social and economic benefit . Here are three varieties of functional plastic packaging film.Active barrier packaging filmsActive oxygen barrier packaging film is divided into different types and forms of suction -type barrier film .Type oxygen barrier packaging films and traditional barrier packaging films is different, it can not only effectively prevent oxygen through the membrane , and can remain in the oxygen absorbing plastic film bag , so that the oxygen in the bag is kept at a very low level , so as to effectively extend the shelf life of the product . In recent years, Japan and other industrialized countries, the industrial production of the film has been using to good effect.Type oxygen barrier packaging film is a composite film packaging material of an active layer ( oxygen-absorbing layer ) containing . After the film for packaging oxygen , residual oxygen into the packaging bag by heat-sealing layer oxygen layer , the oxygen in the active oxygen layer packaging material and a chemical reaction is consumed . Use oxygen film packaging food and other commodities, do not have in the bag when the package is loaded oxygen agent , simplifying the packaging process , and avoid eating consumers oxygen agents of the state.Oxygen-absorbing material may be reduced iron / sodium chloride , sodium sulfite , or ascorbic acid as a reactant , the product was blended into the resin , or the clear plastic box use of nylon MXD6 / cobalt salts, double polymer / salt -containing side cyclohexene packaging boxes wholesale the polymer blend of the chain / salt and other substances .Type oxygen barrier packaging films can also be blended into the polyolefin reactant oxygen obtained material which is interposed between the sealing layer and an adhesive layer , preparation of a separate layer of oxygen . Although this will increase the number of layers of the composite film , the manufacturing cost increase, but since the inner layer of the barrier layer , the oxygen absorption bag , will exhibit better results.Can Toyo produced a reduced iron and sodium chloride as the catalyst for the oxygen barrier resin blend type material that can be used to cooking bags , infusion packaging bags , containing vitamin C facial mask packaging bags. The determination of the oxygen absorption capacity of the sample film was 0.3ml/cm2, and oxygen absorption amount of the film by blending oxygen change control agent .Toyo canning company has also developed another active packaging film that suction -type barrier packaging film , the film in addition to a barrier outside, but also absorbs moisture film bag structure: the outer layer / active barrier layer / support layer / absorbent layer / inner layer . Application of the water-absorbing film drugs for clinical examination , powdered green tea, etc. , the function of the packaging material itself is hygroscopic , the application of the water-absorbing film does not have to be a desiccant such as silica gel or calcium chloride and loaded with the contents of the bag sealed.Japan shared printing company also successfully developed a hygroscopic packaging materials, is now developing applications in pharmaceuticals, electronic components and other packaging .Antimicrobial barrier filmAntibacterial nano technology and co-extruded cast process of combining , the development of antibacterial barrier packaging films, for extending the shelf life of food , showing good results , used in packing nut achieved good results.Antimicrobial barrier film structure is : PE40/AD10/EVOH20/AD10 / antibacterial PE40, a thickness of 120m. The film middle layer excellent barrier properties of EVOH resin , the resin is a very good barrier properties , can shield a special flavor and prevent mildew in storage during the betel nut ; inner polyethylene layer using antibacterial , antifungal enhancement effect, while it has good sealing performance , the operation provides good conditions bag ; ordinary polyethylene outer layer , in order to maintain a low cost.Antimicrobial barrier film produced by first dispersing agent aids the process of nano antibacterial agent, and then mixed with polyethylene , pelletized with a twin screw extruder to obtain an antibacterial master batch of polyethylene , polyethylene masterbatch with an antibacterial of the polyethylene resin mixed to obtain antimicrobial polyethylene pellets for co-extruded composite use.Betel nut product processed by special request product pure taste, aroma, traditional betel plastic composite packaging shelf life of about three months or so, antimicrobial barrier packaging shelf life of at least six months . The antimicrobial barrier film bag packaging costs have a greater advantage, cost plastic composite bag ( 64 g bags ) of 0.15 yuan / month, while the nano-antibacterial barrier bag approximately 0.11 yuan / month, to reduce costs by more than 25% . Practice shows that the antimicrobial barrier film for packing nut can not only greatly extend the shelf life of the product, reduce spoilage of goods , but also to reduce packaging costs . Antimicrobial barrier film is a worthy of further study , to promote clam shells for sale new products.VCI plastic filmAlso known as gasification of rust film , it is the film vapor corrosion inhibitor (VCI) mixed in polyethylene plastic film made ??of VCI .At room temperature , having a high vapor corrosion inhibitor molecules than air gasification , the release of molecules ( volatiles ) from the film into the closed package space. Once in contact with the vapor phase corrosion inhibitor of the metal surface of the package , i.e. its molecular moisture concentration was decomposed to form free ions dissolved in the electrolyte. Ions in the electrolyte reacts with the ions VCI , substituted molecules attached to the metal surface of the metal , the metal corrosion inhibiting electrochemical reaction occurs . The vapor phase corrosion inhibitor molecules evaporate slowly and gradually , so that space is always packaged in a " saturated " state, to achieve long-term stability of the rust.VCI has a polyethylene features: without salt clamshell boxes , corrosive gases, high temperatures , high humidity affect the outside layer of the product packaging VCI antirust film , you can play a powerful anti-rust function , rust effect is significant to overcome the traditional method is not sufficient to protect the product drawbacks , especially for metal , machinery and electronic products in the processing, storage, transportation and foreign import and export of sea products of high quality rust-proof requirements.VCI packaging applications when high efficiency . Available in bags , can also use tape, stapler and other simple sealing can be easily achieved rust , packaging automation ; provincial workers, save time , reduce costs and overall economic efficiency significantly . In addition, environmental protection and good , no oil , because oil will not cause serious pollution to the environment. Meanwhile, the long- time anti-rust , maritime protection up to 2 years , storage protection up to five years. Finally , VCI antirust film transparency is good , do not open the package you can see the status of the membrane of the object.As a rust-proof packaging , more traditional anti-rust process can be less five processes, reduce the amount of manpower and material resources VCI film. The traditional rust process: product Equipment rust on rust removing residual oil dry Packaging ??Transport open the package to the oil use . The VCI film rust process: product VCI film packaging ??Transport open the package to use.For the rust VCI film packaging with traditional packaging methods were compared using steel HT300 done a salt spray, humidity , indoor storage of the clear plastic box packaging three groups compared. Among them, the salt spray, humidity test , using VCI plastic film packaging steel later than oiled plastic film packaging rusty time ; stored indoors plastic packaging box , both of which are 180 days does not rust.Starting in 2001 , the domestic auto companies have adopted a VCI film packaging instead of the original packaging oiled proved using VCI film packaging has many advantages, including superior anti-corrosion effect , a good working environment , compared to comprehensive package of low cost , welcomed by users .Through three functional varieties of plastic packaging film presentation, we learned that not only broaden the functional film packaging film applications, and to achieve economic and social benefits double harvest.
