High-Clarity PVC Packaging Film

Technical Parameters

Material Selection Guide

The key criteria for packaging film are the required clarity (haze level) and the automated equipment's film thickness tolerance.

• Clarity Grade: For premium display packaging, specify the "Super Clear" grade (<1.0% haze). Standard clear film is suitable for functional covers.

• Processing Method: If the film is to be sealed via RF welding, confirm the anti-static additives do not interfere with the welding signal.

• Phthalate Content: For consumer-facing products (especially toys/infant items), request a non-phthalate plasticizer formulation.

Manufacturing and Tailoring

Production focuses on achieving a flawless, high-clarity surface via specialized calendering or casting techniques.

• Haze Control: The calendering temperature and cooling rate are precisely controlled to minimize crystallinity and thermal stress, which cause haze.

• Core Diameter: Film rolls can be supplied on various core sizes (e.g., 3 or 6 inch) to match the feed requirements of high-speed packaging equipment.

• Inspection: Automated optical inspection (AOI) systems are used to identify and flag any internal defects or surface scratches that would compromise clarity.

Deployment FAQ

• Q: Does this film yellow over time in storage?

  A: The formulation includes UV stabilizers that minimize yellowing under standard interior lighting. For long-term sun exposure, a specific high-grade UV package is required.

• Q: Can the film be printed on?

  A: Yes, the film is compatible with high-speed flexographic or screen printing for logos and product information, typically using specialized inks designed for flexible PVC.
