Tell you how to choose a food vacuum bag.food vacuum bag

Vacuum food packaging bags can be seen everywhere in daily life. There are requirements for the selection and use of vacuum bags and their colors. Today, the editor will explain how to choose vacuum bags for food packaging.

1: Vacuum bags are divided into single layer and multi-layer

Ordinary vacuum bags are made of PE single-layer material, which can be vacuumed. However, the damage rate and leakage rate of vacuuming are relatively high, but the cost is low. Many customers choose single-layer PE bags as vacuum bags to save costs. Good vacuum bags are made of multi-layer composite materials, such as nylon/PE. This is a two-layer composite bag, which is sturdy and will not leak when vacuuming. Currently, most food packaging bags use multi-layer composite bags as vacuuming bags.

2: Selection of materials with thickness and special properties

Different materials for vacuum bags with different thicknesses and properties should be used to pack different foods. For heavy products, choose thick materials, and for light products, choose thin materials to save costs. Of course, the thicker the material, the higher the cost, but it will also be stronger. Different foods have different properties, such as choosing oil resistant materials for salt baked foods with high oil content, choosing acid and alkaline resistant materials for kimchi foods with high salt content, and choosing high-temperature resistant materials for products that require high-temperature disinfection or steaming.

When making packaging bags, it is important to inform the packaging manufacturer of the requirements, including what products to use, and any special requirements for the products. Only by understanding specific details can we customize the packaging bags that best match the products and avoid problems during use.
