AI Technical Summary

Technical Problem

Existing plastic films have low reflectivity during cold chain transportation, causing the packaging to heat up. They are not waterproof and breathable at the same time and have poor flame retardancy.

Method used

It adopts a composite structure of a high-density polyethylene non-woven fabric layer and a polyimide fiber layer. The high-density polyethylene non-woven fabric layer has high reflectivity and waterproof and breathable properties, and the polyimide fiber layer has flame retardant and heat-insulating properties. The composite fabric is formed by bonding through an adhesive layer.

Benefits of technology

It effectively isolates the influence of external temperature during cold chain transportation, keeps the temperature of packaged items stable, and has waterproof, breathable and flame retardant properties.

Abstract

The utility model relates to a composite fabric for cold chain transportation, which comprises an outer layer and an inner layer, the outer layer is a high-density polyethylene non-woven fabric layer, and the inner layer is a polyimide fiber layer. The composite fabric is made of the high-density polyethylene non-woven fabric layer and the polyimide fiber layer, and the advantages of the high-density polyethylene non-woven fabric layer and the polyimide fiber layer are integrated on the composite fabric, so that the composite fabric not only has the waterproof air permeability and high reflectivity of the high-density polyethylene non-woven fabric layer, but also has the heat insulation property and flame retardance of the polyimide fiber layer; and meanwhile, the heat preservation property of the flocculus structure of the polyimide fiber layer and the high reflectivity of the high-density polyethylene non-woven fabric layer have a synergistic effect, so that the influence of the external environment on the temperature of the packaged article is weakened together.
