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...

Why does PET strapping have good tensile and elastic properties?
1. Characteristics of molecular structure High crystallinity: PET is a polymer with high crystallinity, and materials with high crystallinity typically have stronger mechanical properties, including tensile strength and elasticity. The crystalline structure tightly arranges PET molecules, which helps to enhance the strength and durability of the material. The long-chain structure of molecular chains: PET molecules contain long and strong molecular chains, and the interaction forces between molecular chains (such as van der Waals forces, hydrogen bonds, etc.) make the material have high tensile resistance. Due to the relatively strong traction of molecular chains, PET can exhibit good ductility and tensile properties under stress. 2. Stretching process during manufacturing Orientation: During the production process, PET strapping is usually subjected to thermal stretching treatment. By stretching PET film under heating, the molecular chains in the material can be arranged more neatly along the stretching direction. After thermal stretching, the structure of PET molecules becomes more ordered, which not only improves the tensile strength but also enhances the elasticity of the material. Directional stretching: During the hot stretching process, PET molecular chains will be arranged more parallel in the longitudinal direction, and this oriented molecular structure makes PET strapping have significant tensile strength....

Application of PP Strapping in Logistics Field
1. Binding and fixing of goods Stable goods: PP strapping is commonly used to bundle and secure various goods during logistics transportation, such as cardboard boxes, wooden boxes, pallets, bulk materials, etc. It can ensure that the goods will not loosen, move or be damaged during transportation. Enhanced stability: Using PP strapping can effectively improve the stability of goods and reduce the risk of damage caused by vibration or friction during transportation. 2. Tray packaging PP strapping is one of the most commonly used materials in pallet packaging. It firmly fixes the goods on the pallet, ensuring the stability and safety of the pallet during transportation. The common practice is to wrap the PP strapping around the pallet and then tighten it to prevent the goods from sliding or tipping over. 3. Container cargo fixation When transported in a container, the goods are prone to displacement due to limited space inside the container. PP strapping can fix the goods inside the container, reduce the shaking and collision of the goods, and prevent damage caused by vibration or bumps during transportation. 4. Identification and tamper proof measures In some cases, PP strapping can be used for tamper proof protection of products....

How to determine the tensile strength of PP strapping band
Determining the tensile strength of PP (Polypropylene) strapping involves measuring the force required to break the strapping material under tension. Tensile strength is an important property because it indicates the maximum load the strapping can bear before it fails. Here’s how you can determine the tensile strength of PP strapping: 1. Prepare the Equipment Tensile Testing Machine: This is the primary tool used for testing tensile strength. It can apply a controlled pulling force on the PP strapping until it breaks. PP Strapping Sample: Ensure the sample is cut into a standard length, typically around 200 mm to 300 mm, depending on the testing machine specifications. Grips/Clamps: These are used to hold the ends of the strapping material securely in place while the machine applies the force. 2. Set Up the Test Place the PP strapping in the tensile testing machine’s grips. Ensure the sample is aligned correctly to avoid any slippage during the test. The machine will pull the sample in a straight line (usually at a specific speed, such as 100 mm/min). This is typically done according to standards such as ASTM D3759 or ISO 527. The test should be conducted at room temperature unless otherwise specified, as...
