The material selection of food vacuum bags is an important factor related to food quality and safety. The main materials of food vacuum bags include polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), etc. Among them, PE and PP are more commonly used food packaging materials, while PVC is less used in food packaging because of its poor hygienic properties.
PE is a relatively safe food packaging material, with good barrier properties, high temperature resistance and impact resistance. PE vacuum bags are mainly used to package cooked food, pickled food, soy products and other foods that need to be preserved in vacuum. When choosing PE vacuum bags, attention should be paid to choosing products with no peculiar smell, no impurities, and uniform color.
PP is also a commonly used food packaging material, its hygienic performance is slightly worse than PE, but it has better transparency and gloss. PP vacuum bags are mainly used to package cold vegetables, condiments, aquatic products and other foods that need to be stored in vacuum. When choosing PP vacuum bags, attention should be paid to choosing products with high transparency, good toughness and no peculiar smell.
In addition to PE and PP, one of the more commonly used food vacuum bag materials is nylon/polyester (PA/PET). The vacuum bag of this material has good barrier properties and high temperature resistance, as well as good transparency and gloss. PA/PET vacuum bags are mainly used to package cooked foods, cold dishes, condiments and other foods that need to be stored in vacuum. When choosing PA/PET vacuum bags, attention should be paid to choosing products with good toughness, high transparency and no peculiar smell.
In short, choosing the right food vacuum bag material is an important part of ensuring food quality and safety. When choosing, it should be comprehensively considered according to the type of food packaged, storage time and use environment and other factors to ensure that the selected vacuum bag material can meet the needs of food packaging. In addition, attention should also be paid to the selection of qualified products from formal channels and avoid the use of counterfeit and shoddy products.
In addition to choosing the right material, the following points should be paid attention to when using food vacuum bags:
1. Vacuuming: When using food vacuum bags, the food should be completely vacuumed to avoid contamination of the food in the bag. , should also pay attention to the degree of vacuuming, to avoid excessive vacuuming caused by deformation or rupture of food.
2. Tightness: The tightness of the food vacuum bag is an important factor to ensure the quality and safety of the food. When using, it should be ensured that the sealing of the food vacuum bag is good to avoid air leakage or leakage.
3. Storage method: Attention should also be paid to the storage method of food vacuum bags. Food vacuum bags should be placed in a dry, cool, and ventilated place, avoiding direct sunlight and high temperature environments. At the same time, care should also be taken to avoid placing food vacuum bags in a contaminated environment to avoid contamination of food.
4. Safety: When using food vacuum bags, attention should be paid to safety issues. The use of expired food vacuum bags or counterfeit and shoddy products should be avoided to avoid contamination of food or endangerment to human health. At the same time, attention should also be paid to the correct use of food vacuum bags in accordance with the instructions for use.
In short, paying attention to the above points when choosing the right food vacuum bag material and using it is an important part of ensuring food quality and safety. When using food vacuum bags, attention should also be paid to regular cleaning and disinfection to ensure the hygienic quality of food.
