Overview
Pink stretch film is a specialized polyethylene film used primarily in logistics and industrial packaging. The pink coloration serves both functional and branding purposes, allowing for easy identification of wrapped items while maintaining all the beneficial properties of standard stretch film. Manufactured through blown film extrusion, the product contains pigments that meet FDA and EU food contact regulations when specified. Unlike clear variants, colored films like this often incorporate additional UV stabilizers to prevent color degradation during outdoor storage or transport.
Physical and Chemical Properties
The base material is linear low-density polyethylene (LLDPE), typically with a thickness range of 15-30 microns. The pink coloration comes from FDA-approved pigments that don't significantly alter the film's mechanical properties. Standard grades offer 200-300% stretch capacity with good cling properties. Key performance metrics include puncture resistance (commonly 200-400g/25μm) and tear strength (both machine and transverse direction). The film maintains flexibility in temperatures ranging from -60°C to 60°C, though optimal performance occurs between -20°C and 40°C. Color stability varies by manufacturer but typically withstands 3-6 months of outdoor UV exposure without significant fading.
Main Applications
Industrial shipping: The pink color enables quick visual identification of specific shipments or product lines in warehouses and distribution centers. Many logistics operations use color-coding to distinguish fragile items, temperature-sensitive goods, or priority shipments. Retail displays: The distinctive color creates eye-catching product bundling for in-store promotions. Some manufacturers produce custom shades for brand-specific packaging solutions. The film also sees use in agriculture for silage covering, where the color helps reflect certain light wavelengths to regulate temperature.
Safety and Storage
As a polyethylene product, pink stretch film is chemically inert and non-toxic under normal use conditions. However, the pigments may contain trace heavy metals, so food-grade certification should be verified for direct food contact applications. Storage recommendations include keeping rolls in their original packaging until use, maintaining temperatures between 10°C and 25°C, and avoiding compression that could deform the roll cores. Proper storage extends shelf life to 12-18 months without significant performance degradation. Used film should be recycled according to local plastic film recycling guidelines.
B2B Procurement Guide
Industrial buyers should specify requirements in these key areas: film thickness (microns), roll width and length, core diameter, stretch percentage, and UV stabilization level. Color consistency across batches is particularly important for branding applications. Leading manufacturers include Sigma Stretch Film, Berry Global, and Intertape Polymer Group. MOQs typically start at one pallet (40-80 rolls), with pricing tiers based on order volume. Consider requesting samples to test colorfastness and mechanical properties under your specific application conditions. Some suppliers offer private labeling for large orders.
