China Coil Wrap Film - Reliable Stretch Film Suppliers & Factory for Efficient Bundling Solutions
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 main protective benefits of wrapping film?
Wrapping film provides a high level of protection by being waterproof, dustproof, and resistant to loosening. It effectively prevents scratches, abrasions, and other physical damage to the cargo during transit.
How does manual wrapping film differ from machine-use wrapping film?
Manual wrapping film is designed for hand operation, featuring lighter rolls (approx. 4-5 kg) and lower tensile strength requirements. Machine-use wrapping film is heavier (approx. 15 kg) and requires high tensile strength and an elongation rate of up to 300%.
What thickness should I choose for wrapping film?
Wrapping film thickness typically ranges from 15μm to 50μm. The ideal thickness depends on the weight, shape, and sharpness of the load you need to secure.
What is metallocene polyethylene (MPE) and why is it used?
Metallocene polyethylene (MPE) is the premium raw material used to make high-quality wrapping film. It offers superior puncture resistance, stretchability, and overall performance compared to standard polyethylene.
Does wrapping film come with adhesive properties?
Yes, wrapping film is available with either single-sided or double-sided adhesive properties, allowing you to choose the level of cling and stability required for your specific packaging needs.
