Types of express packaging bags

A bag used for packaging documents, clothing, materials, items, etc. in the express delivery industry. Common paper types include document bags, envelopes, etc., while plastic types include woven bags, plastic bags, cushioning bubble bags, bubble wrap, etc. The most commonly used among them is the plastic express bag made of polyethylene material, which has the characteristics of low cost, easy use, and good waterproof performance.

Plastic film packaging bag: a bag type packaging product made mainly of resin, processed through blown film, die-cutting, printing, and sealing, which can be loaded with express delivery during the delivery process.

Air cushion film packaging bag: a bag type packaging product made of resin as the main raw material, extruded double-layer film vacuum composite formed air cushion film, and processed through composite, die-cutting, printing, and bonding to load express packages.

Plastic woven fabric packaging bag: a bag type packaging product made from resin as the main raw material, extruded and stretched into flat silk, and processed by weaving, printing, sewing, etc., which can be loaded with express delivery.

Choosing the appropriate courier packaging bag and preventing damage is a challenge that e-commerce companies cannot ignore. To select cost-effective express packaging bags from the diverse categories in the packaging market, it is not only necessary to classify them based on different packaging materials, shapes, sizes, and other details, but also to distinguish them based on the basic requirements of the packaging bags. From the perspective of physical testing of express packaging, there are basic testing requirements such as thickness, thickness limit deviation, tensile strength, nominal strain at break, right angle tear force, heat sealing strength, resistance to pendulum impact, puncture strength, etc. The corresponding testing instrument is the THI-1801 thickness gauge, which is used for precise thickness measurement of various materials such as plastic film, thin film, paper, foil, silicon wafer, etc. TSL-1002 electronic tensile testing machine is used for quantitative testing of mechanical indicators such as tensile, modulus, tear, strength, peel, puncture, compression, and sliding of plastic films, sheets, rubber, composite films, paper, foil, fibers, and other products. ETT-1501 Tear Tester, used for testing the tear resistance of materials such as films, sheets, paper, cardboard, textiles, and non-woven fabrics. HSL-697 heat sealing tester is used to determine the heat sealing performance parameters of various plastic films, composite films, aluminum foils, PVC hard sheets and other materials. PIT-1701 pendulum impact tester is used for precise determination of the resistance to pendulum impact of materials such as plastic film, thin film, composite film, aluminum foil, paper, etc. For more product details, please visit the website of Jinan SYSTEST Technology Co., Ltd. or contact us to help packaging material manufacturers control product quality issues.
