How to identify the quality of food packaging bags

In daily life, exquisitely designed and practical food packaging is everywhere, whether in shops, supermarkets, or in every household. Bag It's hard to imagine what the scene would be like if unpackaged food were delivered to every consumer. In fact, food packaging Bag is like the close-fitting clothing of food, and has become an inseparable part of food. It not only protects and promotes food, but also directly or indirectly affects food quality. Below, Shunxingyuan Packaging, a professional flexible packaging manufacturer, will talk about how to choose high-quality food packaging bags.

I. How professional food companies choose Food Bags Bag

Different foods have different chemical compositions and properties, and the requirements for packaging Bag protection are also different. Therefore, professional food producers must choose appropriate packaging bags according to the food's properties, shape, and production process. For example, a well-known brand of salt-baked chicken, after high-temperature 121°C sterilization, in order to maintain the color, aroma, and taste of the food, high-temperature retort pouches with high temperature resistance and high barrier properties (extending the shelf life of the food) are required; while tea packaging should have high oxygen barrier, high moisture barrier, high light barrier, and high aroma barrier properties, otherwise it will lead to oxidation of tea active ingredients, moisture absorption and mildew, and aroma dissipation. The mode of transportation is also a consideration when choosing packaging bags. For example, a certain food product may be shipped by sea, and its temperature will rise after floating at sea for a period of time, so the product packaging is required to ensure that it blocks everything from the outside world and ensures that the product does not deteriorate.

II. Choosing inferior packaging Bag What are the effects?

Because Food packaging bags are in direct contact with food, long-term use of inferior food packaging Bag contact materials, their toxic and harmful substances will gradually seep into the food during storage and use, accumulate in the body, leading to chronic poisoning, and causing direct harm to the consumer's body. In addition, improper use of qualified Food packaging bags may also cause food contamination. For example, using non-high-temperature resistant food and packaging to wrap high-temperature retort food may cause chemical reactions in the food, producing toxic substances.

III. How to identify the quality of food packaging bags

1. Smell with your nose; some inferior Food packaging bags have solvent residues and a pungent odor.

2. Observe for delamination; some inferior Food packaging bags have low composite strength and are prone to delamination.

3. Check whether the mouth of the packaging bag is sealed firmly and whether it can withstand a certain amount of tearing and pulling.

4. Choose a well-managed packaging bag supplier, and avoid choosing small workshop packaging material suppliers that use inferior raw materials. 。

5. High-quality packaging bags must meet relevant industry and national quality inspection standards before leaving the factory.
