What is Polythene Sheeting?

Polythene sheeting is a plastic film made from polyethylene, a polymer derived from ethylene gas. Known for its flexibility, strength, and affordability, it’s produced in rolls, sheets, or bags and used to cover, protect, or wrap objects across countless scenarios.

Key Properties

● Lightweight: Easy to handle and transport.
● Waterproof: Shields against moisture and rain.
● Durable: Resists tearing and punctures (depending on thickness).
● Flexible: Conforms to various shapes and sizes.
● Cost-Effective: Affordable for both industrial and personal use.

Manufacturing Process

Polythene sheeting is made through a process called extrusion:
1. Polyethylene resin pellets are melted at high temperatures.
2. The molten plastic is forced through a die to form a thin film.
3. The film is cooled, stretched, and wound into rolls of varying widths and thicknesses.
This process, perfected by companies like Dongguan Zhiteng Plastic Product Co., Ltd. with over 23 years of expertise, allows for customization in thickness, color, and additives to suit specific needs.
