Import 20gp 40gp 40hq Heat Insulation Container Bag — Buy in wholesale FOB from Supplier in China

The 20gp 40gp 40hq Heat Insulation Container Bag is a thermal liner system designed to line standard shipping containers for temperature-sensitive cargo transport. The liner features a multi-layer composite structure combining aluminum foil, polyethylene, aerogel insulation, woven fabric, polyamide, and PET layers (alu/pe/aerogel/woven fabric/pa/alu/pet), creating a comprehensive thermal barrier. Each size variant is precisely cut to match container internal dimensions: 20gp measures 6m × 2.35m × 2.35m, 40gp measures 12m × 2.35m × 2.35m, and 40hq measures 12m × 2.35m × 2.7m. The liner weighs 18kg for 20gp, 26kg for 40gp, and 29kg for 40hq configurations, with a uniform thickness of 0.2mm across all variants.

The insulation material achieves a heat reflectivity rating of 96 percent, meaning it reflects back most infrared radiation that would otherwise be absorbed through the container walls. The tensile strength measures 370N/25mm endwise and 360N/25mm broadwise, indicating strong resistance to tearing forces during installation and cargo handling. Elongation at break reaches 27 percent endwise and 24 percent broadwise, providing flexibility during installation while maintaining structural integrity. The moisture permeability rating of 1.1g/m2 per 24 hours and oxygen permeability of 101.86×10-6 ensure the liner does not trap humidity inside the container, preventing condensation damage to sensitive goods. Temperature resistance spans from -70°C to +100°C, making these liners suitable for frozen food transport, pharmaceutical logistics, and hot cargo operations alike. The bursting strength of 890N demonstrates durability against point loads and mechanical stress during shipping.

These container thermal liners are purchased by cold chain logistics companies, food export/import businesses, pharmaceutical distributors, and chemical manufacturers requiring temperature-controlled ocean freight. The typical application involves installing the liner inside the container using the four lid attachment points and zipper closure system, creating an insulated envelope around the cargo. Buyers typically order MOQ (minimum order quantity) configurations and arrange for sea freight under standard Incoterms, with delivery timelines varying based on production scheduling and shipping routes. The product serves as a retrofit solution that transforms standard dry containers into temporary thermal containers without permanent modification.
