China Suppliers Factory for Coil Wrap Film - High-Quality Stretch Film for Bundling Goods
What are the advantages? There 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
What are the primary benefits of using wrapping film?
Wrapping film provides a high level of protection against water, dust, scratches, and loosening. It is durable, secure, tear-resistant, and offers significant packaging cost savings compared to cardboard or heat-shrinkable films.
How do manual and machine-use wrapping films differ?
Manual-operated wrapping film is lighter (around 4-5 kg per roll) for easy handling and has lower tensile requirements. Machine-use wrapping film is heavier (about 15 kg per roll) and designed with high tensile strength and an elongation rate of up to 300% to withstand machine application.
What is the standard thickness of wrapping film?
Wrapping film thickness typically ranges from 15μm to 50μm, allowing you to choose the appropriate thickness based on the load type and protection requirements.
What raw materials are used to make high-performance wrapping film?
High-performance wrapping film is manufactured using metallocene polyethylene (MPE). MPE offers superior stretchability, puncture resistance, and load-retention performance compared to standard polyethylene.
How do I choose the correct width for wrapping film?
For manual application, tools and rolls typically range from 300mm to 500mm in width. For automated machine applications, a standard width of 500mm is generally used.
