PE biodegradable bag

Introduction to PE Biodegradable Bags

Core conclusion: PE biodegradable bags are environmentally friendly plastic bags made from polyethylene (PE) as the substrate and added with biodegradable masterbatch (such as PLA, PBAT, starch based). The core value is "retaining the basic function of PE bags+being biodegradable in the natural environment". They can be decomposed into water and carbon dioxide by microorganisms in composting, soil or seawater environments without residue, and are suitable for various packaging scenarios with environmental requirements, solving the problem of "white pollution" of traditional PE bags.

Basic definition and core characteristics

PE biodegradable bags are environmentally friendly packaging made by mixing biodegradable polymer materials into ordinary PE materials and using blown film and bag making processes.

• Core components: PE substrate (LDPE/HDPE/LLDPE)+biodegradable masterbatch (accounting for 15% -40%)+environmentally friendly heat sealing process

• Degradation characteristics: In accordance with the national standard GB/T 20197 or the EU EN 13432 standard, under specific conditions (temperature 58 ± 2 ℃, humidity 55 ± 5%, presence of microorganisms), the degradation rate is ≥ 90% within 180 days, and ultimately decomposes into harmless substances

• Basic function: Retain the moisture-proof, lightweight, load-bearing, and waterproof characteristics of PE material, and provide the same user experience as ordinary PE bags

• Core difference: Different from ordinary PE bags, it can naturally degrade without polluting the environment; Different from fully biodegradable bags (such as pure PLA bags), PE biodegradable bags have lower cost, better toughness, and are suitable for more scenarios
