Wrapping film quick pass card
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.
