China Coil Wrap Film Suppliers - High-Quality Stretch Film from Trusted Factory for Secure Bundling and Storage
What are the advantages? Tn here are mainly a few points:
- High level of protection: waterproof, dustproof, and resistant to loosening, which also helps prevent damage to the cargo from scratches and abrasions.
- Durable and secure: exhibits strong tensile and retraction forces, excellent tear- and puncture-resistance, and can secure cargo with sharp edges.
- Cost savings: Compared to cardboard boxes or heat-shrinkable film, this method significantly reduces packaging costs.
How are they categorized? It mainly depends on their usage:
- Manual-operated wrapping film: Operated by hand, with low requirements for tensile strength. Each roll weighs lightly (approximately 4-5 kg).
- Machine-use wrapping film: Designed for use with machinery. It requires high tensile strength and elongation rate (elongation rate up to 300%). Each roll is relatively heavy (about 15 kg).
How to choose? Focus on these key factors:
- Consider the width: Hand tools typically range from 300mm to 500mm, while machine tools usually have a width of 500mm.
- Check the thickness: It typically ranges from 15μm to 50μm.
- Determine the adhesive properties: there are single-sided and double-sided adhesives.
- Look at the raw material: It’s made from metallocene polyethylene (MPE). Its performance is generally superior to that of regular polyethylene.
Frequently Asked Questions
Q: What are the primary protective benefits of wrapping film?
Wrapping film provides a high level of protection by being waterproof, dustproof, and resistant to loosening. It also helps prevent scratch and abrasion damage to your cargo.
Q: How does wrapping film help reduce packaging costs?
Compared to traditional packaging methods like cardboard boxes or heat-shrinkable film, wrapping film significantly reduces overall material and packaging costs.
Q: What is the difference between manual and machine-use wrapping film?
Manual-operated rolls are lightweight (4-5 kg) and designed for hand wrapping with lower tensile requirements. Machine-use rolls are heavier (about 15 kg) and engineered for high tensile strength and elongation rates up to 300%.
Q: What dimensions and thicknesses are typical for wrapping film?
Widths typically range from 300mm to 500mm for manual use, and 500mm for machine use. The standard thickness ranges between 15μm and 50μm.
Q: Why is metallocene polyethylene (MPE) preferred for wrapping film?
MPE is preferred because it offers superior performance, tensile strength, and durability compared to regular polyethylene raw materials.
