Protecting food safety: Strict requirements for (PE) adhesive coating of food packaging

Publish Time: 2024-11-27

In the field of food packaging, (PE) adhesive coating is responsible for protecting food quality and safety. It must strictly abide by a series of safety and hygiene guidelines to build an "invisible protective wall".

Regulatory standards are the cornerstones of compliance. Regulatory agencies in various countries have formulated detailed specifications. For example, the EU's food contact material regulations have given strict indicators for the migration limit of chemical components of (PE) adhesive coating. my country also has the GB 4806 series of standards, which strictly prohibit the coating from containing harmful heavy metals such as lead, mercury, and cadmium. Control from the source to prevent these substances from "penetrating" into food through packaging and harming the human body. Take lead as an example. Long-term intake of trace lead will accumulate in the human body and damage the nervous system and hematopoietic system. Strict compliance with standards can ensure that the coating is free of "lead problems" and protect the health of consumers.

Material purity is related to the core of safety. The entire production process of (PE) adhesive coating requires strict selection of food-grade polyethylene raw materials, removing impurities and recycled material pollution, and ensuring purity and non-toxicity. The additives in the synthesis should be selected with great care. Plasticizers can only be used in licensed varieties and in controlled quantities to avoid excessive amounts of phthalates. There have been cases of food packaging contamination due to the illegal use of large amounts of phthalate plasticizers, which has far-reaching harm. We must strictly adhere to purity and avoid such "toxic packaging" risks.

Stability and anti-migration are key lines of defense. The packaging is exposed to various types of food and different environments, and the coating must be chemically stable. Acidic foods and oils are "tests", and the coating cannot be corroded or decomposed, causing component migration. In the face of edible oil packaging, the coating is stable and does not react with oils and fats, and does not release harmful substances, preventing plasticizers, antioxidants, etc. from "smuggling" into the oil. Scientific research and testing escort to meet standards, enterprises use advanced equipment to simulate food contact, such as using n-hexane to simulate oils and ethanol to simulate alcohol, test migration, and ensure safety.

Hygiene control runs through the entire life cycle. From dust-free and sterile production workshops to prevent the entry of microorganisms, to moisture-proof, insect-proof and sun-proof storage and transportation to avoid coating deterioration, strict hygiene is observed in every link to extend the shelf life while ensuring that the packaging is "untainted by mud". (PE) adhesive coating uses high standards and strict requirements to protect food safety in the food packaging arena and help food reach consumers' tables.
