1. Commonly used materials for mask bags:
The mask bag can be made of BOPP, PE, and PE compounded with Pet.
The bag made of BOPP has good transparency and low cost, and is an ideal product for disposable packaging;
The mask bag is made of PE material, the transparency is average, but the bag made has good toughness, the bag is smooth and easy to pack when packing the mask, and it can reduce labor costs, etc.;
2. Four reasons for deciding which composite process to choose for mask ziplock bags:
The dry reprocessing of mask ziplock bags requires sufficient drying, but for some high-end packaging applications, there may be problems with the amount of solvent residue. Similar to these uses, you can choose the extrusion compound processing method.
The extrusion and multiple processing method of the mask ziplock bag is relatively low cost, so if both methods can be used, the extrusion multiple processing method is adopted.
The resin used in the extrusion of mask ziplock bags has no high temperature resistance, so it cannot be used for cooking or boiling treatment that requires high temperature resistance. The dry re-use adhesives are used according to different purposes, and basically all purposes can be used.
In the dry compounding process of mask ziplock bags, 2~4g/㎡ (solid content) is coated on the substrate, and the stiffness becomes stronger after the adhesive is cured. When high stiffness is required, dry reprocessing can be selected.
The composite mask bag PE+pet is used for vacuum packaging, which has the advantages of good sealing effect and long storage time.
The blue self-supporting bottom mask packaging bag is made of brand-new plastic granules, does not contain recycled materials and fillers, and feels smooth and not rough. The printing color is full and bright, which visually makes customers feel happy. Three-side sealed zipper bags can be used for packaging of clothing, gifts, data cables and other products.
The blue self-supporting bottom mask packaging bag is a composite packaging bag. The mask packaging bag usually adopts a two-layer or three-layer composite structure. The common material combination is CPP composite OPP.
Composite packaging bags such as blue self-supporting bottom mask packaging bags are usually used to package relatively thin and soft products. The protective properties of composite packaging bags can well protect the contents from contamination and damage.
