Three essential elements to know when customizing vacuum packaging bags!

When customizing vacuum packaging bags, in order to ensure that the packaging bags can meet specific needs and ensure the safety and freshness of food, the following three elements must be understood:
1、 Material selection
The material of vacuum packaging bags directly affects the safety and freshness of food. Choosing appropriate materials can ensure that food remains fresh and prevents oxidation and microbial contamination during long-term storage.
Common materials:
1. Nylon (PA): It has good oxidation resistance and corrosion resistance, and is widely used in vacuum packaging of food, medicine, cosmetics and other products.
2. Polyester (PET): colorless, transparent, glossy, with excellent mechanical properties, puncture resistance, and friction resistance. It is one of the commonly used transparent composite vacuum bag substrates.
3. Polyethylene (PE): has low transparency, but excellent gas barrier, oil barrier, and fragrance retention properties. It is relatively inexpensive and suitable for ordinary vacuum bag materials.
Choose the appropriate material combination based on factors such as food type, storage time, and transportation environment. For example, for easily oxidizable foods, PA or PET materials can be chosen; For foods that require long-term storage, materials with excellent barrier properties can be chosen.
2、 Specification and size
Appropriate specifications and sizes can ensure that food is adequately protected inside the packaging bag, while avoiding waste and increasing costs.
Common specifications: There are various sizes and shapes of food vacuum bags, such as 5x7 inches, 6x10 inches, 8x12 inches, etc., suitable for different sizes and shapes of food.
Choose the appropriate size and specifications based on the size and shape of the food. At the same time, pay attention to the capacity and size of the packaging bag to match the food, avoiding inconvenience and waste caused by being too large or too small.
3、 Sealing performance
Good sealing performance is one of the key properties of vacuum packaging bags, which can ensure that food remains in a vacuum state inside the packaging bag, preventing oxidation and microbial contamination.
During the customization process, the manufacturer can be requested to provide a sealing performance test report to ensure that the sealing performance of the packaging bag meets relevant standards.
It is recommended to choose materials and processes with excellent sealing performance, such as using heat sealing technology or ultrasonic sealing technology, to improve the sealing performance of packaging bags. At the same time, pay attention to checking whether the sealing of the packaging bag is flat and firm to avoid the occurrence of air leakage.
