Addictive spicy strips, summer thirst-quenching milk tea, soft and delicious bread, fragrant roast duck ...... All kinds of delicacies we like in daily life are basically inseparable from the exquisite packaging, so have you noticed the packaging material? I believe everyone's first reaction is that most of them are plastic packaging, so what is the production of plastic packaging? Based on the particularity of food, the packaging of food has more stringent requirements than the packaging of other products.

I believe everyone can guess that the plastic used for food packaging materials should not only have the performance of general packaging materials, but also pay special attention to packaging hygiene, which has become an important means to ensure food hygiene, safety and prolong food storage life. So, what are the plastic film standards for food packaging? First of all, it must fully comply with the food packaging hygiene standards. That is, the plastic box itself does not have the migration of toxic substances, non-toxic, odorless, and odorless; the printing box can meet the above standards.

According to the needs of different varieties of food packaging, the use of corresponding packaging materials. Plastic flexible packaging materials for food mainly include polyethylene, polypropylene, polyester, polyamide and other polymer materials. In order to keep food fresh during circulation and provide it to consumers safely and hygienically, food packaging must be inspected for safety. There are many requirements for food packaging performance: such as barrier properties: barrier properties include gas barrier and moisture barrier, a good sealing environment can reduce the probability of food deterioration, improve the quality of preservation. Tensile properties are equally important: the film is subjected to mechanical tension during the packaging process, and during transportation, the product will inevitably be squeezed by external forces, which leads to the packaging film must have sufficient tensile strength to adapt to this environment.

Xiaobian here to teach you a trick, in the choice of outer packaging, you can use the existing on the market and your product characteristics close to the food packaging materials for reference; so after comparing some similar models, select all aspects are most suitable for their own goods packaging type.
