Stretch Wrap Usage & Buying Guide

Stretch wrap, or stretch film, is a commonly used material in shipping and warehouse environments to secure boxes and products on a pallet for transport and storage. As there are various types of films, determining the best one for your specific application can be challenging. Let this guide answer your frequent questions about stretch wrap usage.

What Size Stretch Wrap Should I Use?

Stretch wrap is available in different thicknesses, known as gauges, as well as various widths. Hand-grade films usually range from 12” to 18” in width, while machine-grade rolls often come in 20” widths for use with a stretch wrapping machine. The gauge of the film typically ranges from 37 to 150, with 63 to 80 being the most common. Here are some factors to consider when choosing the correct gauge:

Shape of the Load

Irregular-shaped loads require stronger wrap for more holding power compared to uniform loads of same-sized boxes.

Weight of the Load

Heavier loads need a stronger stretch film. Refer to the chart below for weight-specific guidelines.

What is Pre-Stretched Hand Film?

Pre-stretched film is stretch wrap that is mechanically elongated to nearly its breaking point and then wound onto rolls. This film offers double the strength at half the thickness of standard wrap, making it easier to apply, lighter, and more efficient, providing better load stability, fewer damages, and less waste.

When is Opaque or Colored Stretch Film Used?

Opaque stretch film is used to conceal products or protect contents from theft and UV exposure. Colored stretch films are beneficial for color-coding products, with green often used for eco-friendly items ready for shipment.

Is Stretch Wrap Recyclable?

Only around 5% of stretch wrap is recovered in the U.S. Stretch film is typically composed of linear low-density polyethylene (LLDPE) and falls under category four of recycling programs but often cannot be recycled in curbside bins. Special recycling processes are required for this thin plastic.

Biodegradable stretch film is gaining popularity as an environmentally-friendly packaging solution, replacing traditional plastic stretch films. For businesses importing large quantities, here is key information and storage tips for biodegradable stretch film.

What is Biodegradable Stretch Film?

Biodegradable stretch film degrades naturally over time and is usually made from materials like Polylactic Acid (PLA), Tapioca, and Polycaprolactone (PCL). It performs similar functions as traditional stretch film with the added benefit of biodegradability.

Uses of Biodegradable Stretch Film

Besides protecting and preserving goods during transportation, biodegradable stretch film offers benefits like secure protection from stacking-related damage, UV light, moisture, and dust. It also improves the aesthetic appeal of packaged goods with various color options and decreases environmental impact by using recyclable low-density polyethylene (LDPE).

Cost Savings

Using biodegradable stretch film can lead to cost savings by reducing the film thickness, which can save businesses 15-30% in packaging costs per load.

How to Store Biodegradable Stretch Film in Bulk

Biodegradable stretch film needs careful storage due to its decomposable nature. Here are storage tips for different seasons:

Summer Storage

In high temperatures and humidity, excessive heat may cause the film to melt and stick together. Store the film in the coolest area and consider air conditioning to extend its shelf life.

Winter Storage

In extremely low temperatures, the film can become brittle. Store it in a well-ventilated, insulated area, and use heating equipment if necessary to prevent brittleness.

Frequently Asked Questions

Here are common questions about biodegradable stretch film:

How does biodegradable stretch film work?

Made from plant-based polymers, this film decomposes naturally under conditions like sunlight, moisture, and microbial activity without harmful residues.

How long does it take to degrade?

The time varies depending on the material but generally takes weeks to months within ideal conditions, much faster than traditional plastics.
