I. Product Definition

Stretch film, also known as cling film, is a plastic film with high tensile strength and retractability. It is mainly used for cargo packaging and pallet wrapping, tightly wrapping items together to prevent loosening, dust, moisture, or damage during transportation.

II. Product Advantages

High-strength protection: It has good puncture resistance and tear resistance, effectively preventing transportation damage.

Excellent tensile properties: It can significantly reduce film costs, using less material for the same packaging volume.

Good self-adhesiveness: Single-sided or double-sided self-adhesive, no tape or heat sealing required, easy to use.

High transparency: Convenient for cargo identification and enhances packaging grade.

High-efficiency packaging: Compatible with automatic packaging machines, suitable for high-speed production lines.

Environmentally friendly and recyclable: Meets environmental protection requirements, recyclable, and energy-efficient.
