Production process of PP strapping band
1. Raw material preparation Raw material selection: The main raw material for PP strapping is polypropylene (PP) resin, usually polypropylene plastic particles or resin are chosen as the base material. In addition, according to the requirements, some additives such as antioxidants, anti UV agents, fillers, etc. can be added to improve the performance of PP strapping. Mixing: Based on the characteristics of the required product, additives and PP resin are evenly mixed in the mixing machine to ensure stable quality of the finished product. 2. Extrusion molding Melt extrusion: Heat the mixed PP resin to a molten state and extrude it through the mold of the extruder to form a preliminary polypropylene strip. During this process, plastic particles are melted by heating and forced through a mold to form a thin strip. Forming width control: By adjusting the width and temperature of the mold, the thickness and width of the preliminary strip are controlled. 3. Cooling and shaping Cooling system: The extruded PP strip is rapidly cooled through a cooling groove or cooling roller to prevent deformation and shape it. The cooling process is very important as it directly affects the strength and quality of the packaging tape. Shaping adjustment:...

The essential difference between PP strapping and PET strapping
Raw materials and chemical structure PP strapping: Made of polypropylene, a thermoplastic with lower density and lighter weight. Its molecular structure is relatively simple, mainly composed of propylene monomer polymerization. PET strapping: Made of polyethylene terephthalate, PET is a highly crystalline thermoplastic. Its molecular structure is more complex, with stronger molecular chain arrangement and strength. Strength and tensile strength PP strapping: Compared to PET, PP strapping has lower tensile strength. It is suitable for bundling medium weight goods, but may be prone to breakage or stretching deformation when handling heavy objects. PET strapping: PET strapping has higher tensile strength and stronger toughness, can withstand greater tensile forces, and is suitable for goods with large weight or requiring high-strength bundling. PET strapping is more sturdy and less prone to damage during transportation. Durability and environmental adaptability PP strapping: Polypropylene material has relatively poor resistance to moisture and chemicals, and gradually degrades under the action of ultraviolet radiation, leading to material brittleness. Therefore, it is more suitable for use indoors, in dry and mild environments. PET packing belt: PET has excellent UV resistance, acid and alkali resistance and anti-aging performance, so PET packing belt performs better when used outdoors or in harsh...

The benefits of using PET strapping band in logistics transportation
1.Strong environmental adaptability Adapt to various temperature environments: PET strapping can maintain stable performance over a wide temperature range. Whether in hot summer or cold winter, PET strapping can maintain its strength and flexibility, adapting to various transportation environments. Chemical resistance: PET has good acid, alkali, and chemical corrosion resistance, so even during chemical transportation, PET strapping can remain stable and not easily corroded or degraded. 2.Improve packaging efficiency Easy to operate: PET strapping is relatively easy to operate compared to other packaging materials such as steel strips and plastic strips. When using automated or manual packaging equipment, PET strapping is easy to fasten and adjust, reducing the complexity and time of packaging operations and improving work efficiency. No need for heating and sealing: PET strapping can be easily tied and sealed using a strapping machine, without the need for heating and sealing, reducing packaging costs and operational difficulties. 3.Cost effectiveness Low cost: Although PET strapping has superior performance, its cost is more competitive compared to metal packaging materials such as steel strips. It can reduce packaging costs while ensuring packaging strength, making it a cost-effective packaging choice. 4.Widely applicable Suitable for various industries: PET strapping is suitable for logistics...

Why does PET strapping have tear resistance？
1. Strength and toughness of molecular structure Long chain molecular structure: PET (polyethylene terephthalate) is a highly crystalline polymer with relatively long and orderly molecular chains. Long chain molecules are firmly bound together through interactions such as van der Waals forces and hydrogen bonds, providing strong tensile strength. Due to the ability of these long-chain molecules to disperse external forces, PET strapping is less prone to cracking or tearing under stress. Crystallinity: PET material has a certain degree of crystallinity, and the crystalline region allows the molecular chains to be arranged more orderly in a certain direction. This arrangement increases the strength of the material, enabling it to better withstand external impacts and tensile forces, avoiding breakage or tearing when subjected to tearing. 2. High tensile strength Tensile strength refers to the ability of a material to resist fracture when subjected to tensile force. The tensile strength of PET strapping is high, which means it can withstand significant tensile forces without easily breaking or tearing. Even during the stretching process, PET strapping can distribute stress between molecular chains and will not easily tear. The tear resistance performance is also related to the arrangement direction of the molecular chains. After thermal...

Why can PET strapping adapt to various environments?
PET strapping band can adapt to various environments, mainly due to its excellent chemical properties, physical characteristics, and manufacturing processes. 1. Good temperature resistance High temperature tolerance: PET strapping has good thermal stability and can maintain its structure and properties at higher temperatures. Generally speaking, PET can still operate stably within the temperature range of 80 ° C to 100 ° C. Beyond this temperature, PET may become soft or lose its original tension, but under normal conditions, it can adapt to higher temperatures. Low temperature performance: PET strapping can maintain good toughness and tensile resistance even in low temperature environments. It does not become brittle in cold weather like some plastic materials such as polypropylene. PET still has good ductility and strength at low temperatures, making it suitable for transportation in cold regions. 2. Excellent moisture resistance Water resistance: PET has a low water absorption rate, which can effectively prevent water swelling or performance degradation in humid environments. Even in humid environments, PET strapping can maintain its strength, elasticity, and tensile strength, making it suitable for storage and transportation conditions with high moisture content. Moisture resistance: PET has good chemical stability and is not easily affected by moisture, making...
