There are many types of vacuum packaging bags, how should customers choose

Customers often ask what kind of vacuum bag is good for vacuum packaging dried bamboo shoots, vacuum packaging bacon, vacuum packaging schisandra, vacuum packaging yam and other local specialties. In fact, it depends on the characteristics of the product to choose a vacuum bag of the right material. In terms of performance, it can be divided into non-barrier vacuum bags, medium barrier vacuum bags and high barrier vacuum bags; from the functional point of view, it can be divided into low temperature resistant vacuum bags, high temperature resistant vacuum bags, puncture resistant vacuum bags, shrink bags, self-supporting Bags and zipper bags, etc.

Faced with a variety of packaging materials and different product characteristics, how to choose a suitable vacuum packaging material has become a problem that must be solved in actual production and application

How to choose vacuum packaging bags for different types of products?

Because different products have different requirements for packaging materials, material selection should be made according to product characteristics, including: whether it is easy to deteriorate, factors that cause deterioration (light, water or oxygen, etc.), product form, product surface hardness, storage Conditions, sterilization temperature, etc. A good vacuum bag does not necessarily have many functions, but depends on whether it is suitable for the product.

1. Best vacuum sealer bags with regular shapes or soft surfaces:

For products with regular shapes or soft surfaces, such as meat sausage products, soy products, etc., high mechanical strength of the material does not need to be required, only the barrier properties of the material and the influence of the sterilization temperature on the material need to be considered. Therefore, for such products, packaging bags of OPA/PE structure are generally used. If high temperature sterilization (above 100°C) is required, OPA/CPP structure can be used, or high temperature resistant PE can be used as the heat seal layer.

2. Best vacuum sealer bags with high surface hardness:

Products such as bone-in meat products, due to their high surface hardness and hard protrusions, are easy to pierce the packaging bag during vacuuming and transportation. Therefore, the packaging bags of such products need to have good puncture resistance and cushioning properties. Optional vacuum bags made of PET/PA/PE or OPET/OPA/CPP. If the product weight is less than 500g, you can try to use OPA/OPA/PE structured packaging bags, which have good product adaptability, better vacuum effect, and will not change the shape of the product.

3. The best perishable vacuum sealed bag:

Low-temperature meat products and other products that are prone to spoilage and require low-temperature sterilization do not have high requirements for the strength of the packaging bag, but they require excellent barrier properties. Therefore, you can choose a pure co-extruded film, such as PA/PE/EVOH/PA/ PE-structured films can also be dry-coated, such as PA/PE films, and K-coating materials can also be used. The best vacuum sealer bags for high temperature, PVDC shrink bags or dry multiple bags can be used.
