1. Diverse materials Plastic materials: Common ones include polyethylene (PE), polypropylene (PP), etc. PE material is soft and has good toughness, with certain moisture resistance, suitable for powder materials that do not require particularly high moisture resistance, such as some powder additives used in construction; PP material has good heat resistance and chemical stability, and can withstand a certain degree of acid-base corrosion. It is commonly used in powder raw material packaging in the chemical industry. Paper material: High strength paper such as kraft paper is generally used, which has certain moisture-proof and leak proof properties after special treatment. Paper feeding bags have relatively low costs, are recyclable, and environmentally friendly. They are commonly used in industries such as food and feed that require high hygiene standards and the materials themselves are not easily affected by moisture and deterioration. Composite material: Combining the advantages of various materials, such as aluminum foil composite material, which is composed of aluminum foil and plastic film, it has excellent barrier properties and can effectively prevent the erosion of powder materials by moisture, oxygen, and light. It is particularly suitable for pharmaceutical powders, fine chemical...
