5 Industrial Packaging Bags: A Quick Comparison

• Kraft paper bags are divided into single-layer, multi-layer, and plastic-lined kraft paper bags. They are environmentally friendly and are generally used for packaging in industries such as food (condiments, snack foods, food additives, coffee beans, tea), chemical raw materials, and pharmaceutical raw materials.

• Paper-plastic composite bags are composite bags made of plastic woven bags as the base material and then lined with plastic inner bags. They are commonly known as two-in-one bags or three-in-one bags. Because the inner plastic bags have stronger firmness and waterproofness, they are mainly used to package fertilizers, synthetic materials, explosives, grains, salt, minerals and other powdered or granular solid materials and flexible items to facilitate loading and unloading during transportation.

• Plastic film bags are generally made of thicker PE (polyethylene) or PP (polypropylene). Polyethylene is recognized as the best material for contact with food. The plastic structure is stable and not easily degraded by natural microorganisms. Therefore, it is widely used. It is often used in daily necessities and various foods, and can also be used in chemical raw material packaging.

• Woven bags are made of polypropylene resin as the main raw material, also known as snakeskin bags. They have stronger wear resistance and durability, high recycling rate and can be reused. They are generally used for packaging rice, flour, corn, grains, sugar, building materials, etc.

• Aluminum-plastic film bags generally adopt a three-layer or four-layer structure, providing a more solid packaging foundation. Due to its structural properties, it has strong barrier properties and can isolate moisture, oxygen, and light sources, effectively ensuring the freshness and purity of the goods. It can also be used for vacuum packaging, providing an excellent oxygen-free protective environment, and can be used in precision equipment, medical raw materials, food, etc.

If you are a building materials manufacturer or grain producer and need to transport heavy goods, you can use woven bags, which have strong wear resistance and load-bearing capacity. Aluminum-plastic film bags have good barrier properties and are suitable for products with high sealing and high precision. Plastic film bags are relatively more cost-effective packaging materials and are suitable for the packaging needs of daily necessities.
