Key Specifications and Performance Features

Thickness (Gauge)

Clear stretch films typically range from 40 to 80 gauges (1 to 2 microns per gauge), with thickness directly influencing strength, puncture resistance, and stretchability. Thicker films (70–80 gauge) offer superior durability and load-holding power, making them ideal for heavy, irregular, or sharp-edged products. However, they require more force to stretch and may not be suitable for manual wrapping.

Thinner films (40–60 gauge) are lighter, more economical, and easier to handle—especially in hand-wrapping applications—while still providing adequate protection for lightweight or stable loads. Selecting the right gauge involves balancing cost, load weight, and application method (manual vs. machine).

Width and Length

Standard stretch film widths range from 5 to 80 inches, allowing customization based on pallet size and wrapping equipment. Wider films (60–80 inches) are optimized for automated stretch wrappers, covering more surface area per revolution and reducing wrapping time and labor costs.

Narrower rolls (5–20 inches) are preferred for manual use, especially in confined spaces or when wrapping smaller items, irregular loads, or partial pallets. Roll length varies from 1,000 to 3,000 feet, affecting total usage per roll and replacement frequency. Choosing the right dimensions enhances efficiency and reduces material waste.

Tensile Strength

Tensile strength measures the maximum stress a film can withstand before breaking. High-tensile films can endure significant stretching forces without tearing, ensuring secure bundling of heavy or dynamic loads. This property is crucial for maintaining load stability during transit, especially on uneven roads or in high-vibration environments.

Films with enhanced tensile strength are often multi-layer co-extruded, combining linear low-density polyethylene (LLDPE) with additives for improved toughness. These films resist punctures and maintain integrity under pressure, reducing the risk of product damage or load collapse.
