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...

The Application of Pp Strapping Band
PP strapping band, or polypropylene strapping, is widely used across various industries for packaging and securing items during transport or storage. Its versatility, strength, durability, and cost-effectiveness make it a popular choice for many applications. Here are some common applications of PP strapping bands: Manufacturing and Distribution: PP strapping is extensively used in manufacturing plants and distribution centers to secure products on pallets, ensuring they remain stable and intact during transportation. Shipping and Logistics: In the logistics industry, PP straps are used to bundle and fasten goods tightly so they do not shift or get damaged during shipping. Paper and Printing Industry: PP strapping is ideal for bundling newspapers, magazines, cardboard, and other paper products due to its lightweight nature and resistance to tearing. Construction Materials Packaging: For packaging materials like bricks, tiles, lumber, and other building supplies, PP strapping provides a reliable way to keep loads together. Food and Beverage Industry: It is also used in the food and beverage sector for securing boxes, crates, and other containers, especially when the straps are made from food-grade materials that comply with safety standards. Metal and Coil Industries: PP strapping is utilized to secure metal sheets, coils, rods, and other heavy...

How To Choose The Appropriate Bopp Tape?
The selection of suitable BOPP tape needs to be determined based on specific usage requirements. BOPP tape mainly includes various types such as transparent tape, yellow tape, printing tape, etc. Common application scenarios include sealing, packaging, sealing, labeling, etc. Here are some key factors to consider when choosing BOPP tape: 1. The purpose of tape Sealing: If mainly used for sealing, transparent or yellow BOPP tape is more suitable. Transparent tape is suitable for situations that require invisible sealing, while yellow tape is suitable for situations that require stronger sealing effects. Packaging: For heavy or bulk goods packaging, choose thicker BOPP tape. Generally speaking, the thicker the tape, the stronger its durability and tensile strength. Identification: If identification is required, you can choose to print BOPP tape, which can print the company name, logo or warning information for easy differentiation and recognition. 2. Width and length of the tape Width: Common BOPP tape widths are 48mm, 50mm, 72mm, etc. The selection should be based on the size of the item that needs to be packaged. Generally speaking, widths of 48mm or 50mm are more versatile and suitable for most sealing and packaging needs. Length: Select the tape length based on...
