Plastic wrap has long been one of the most common household items in the public, but ordinary consumers are not chemists. If the packaging is not expressly stated, they do not know what kind of plastic wrap was used to make the product. Can you heat or wrap up fats and oils in the microwave? However, in the future, consumers will be able to buy plastic wraps at a glance. From the packaging, you can learn which cling wraps can be used for food packaging and safety precautions.
The “Plastic Self-Adhesive Film for Food†issued by the AQSIQ and the National Standardization Administration will be officially implemented from September 1. Compared with the 1989 standard, the scope of application of the new standard extends from the original polyethylene (PVC) self-adhesive cling film to other plastic self-adhesive cling film, suitable for food grade resins such as PVC, polyvinyl chloride, polyvinylidene chloride, etc. It is a self-adhesive plastic wrap for foods produced by a single-layer extrusion or multi-layer co-extrusion process as the main raw material; the new national standard requires that the cling film be marked with the net roll weight nominal value and the word “foodâ€, PVC cling film Should be marked with "can not touch with fat foods", "no microwave oven heating", "no high temperature use" and other warning language; other types of plastic wrap, such as can be used for microwave heating, should indicate "can be used in microwave ovens," heating The method and the highest temperature temperature. It is understood that polyvinyl chloride (PVC) film is also a kind of cling film that can be used for food packaging, but it has a certain impact on the safety of the human body. In the new standard, the use of PVC cling film directly packaged meat, cooked food and fat foods was banned. (See: GB10457-2009 food plastic self-adhesive plastic wrap)
"Food plastic self-adhesive plastic wrap" (GB10457-2009) was originally scheduled to be implemented on December 1, 2009. However, on November 27, 2009, the National Standards Committee issued a notice of implementation delay and extended the implementation date to September 1, 2010. (For details, please refer to: Reply Letter Concerning the Approval of Delayed Implementation of the National Standard "Plastic Self-Adhesive Film for Food".)
According to relevant sources, because many companies are still not fully aware of the new standards, some companies do not meet the standards. Therefore, the National Standards Commission postponed the implementation of a new national standard for cling film, giving the company a time of transition and preparation.
