High-Temperature Resistant Heavy-Duty Bags: Breaking Bottlenecks in Hot-Filling Production
In terms of temperature resistance, thermal performance can be customized. Depending on customers’ product characteristics, solutions supporting high temperatures ranging from 80°C to 130°C, or low-temperature applications from -50°C to -20°C are available. For structural design, a three-layer composite construction (tensile-resistant heat-resistant outer layer + barrier middle layer + heat-resistant inner layer) is adopted to preserve mechanical strength and sealing performance under high temperatures. Customization of 4-layer, 5-layer and 6-layer composite structures is also supported to meet special requirements such as enhanced barrier performance, puncture resistance and thermal stability. Multiple base materials are offered to match different product needs, including moisture resistance, light shielding, corrosion resistance and anti-oxidation.
