PE heavy-duty packaging bags (FFS bags) are an efficient and low-cost packaging method. They originated in Europe and have the characteristics of high temperature stability, aesthetics, excellent performance, durability, flexibility, high efficiency and environmental protection. Specifically, PE heavy-duty packaging bags can withstand high-temperature filling at 70-80°C and can withstand tens of relocations and transfers，while maintaining good performance. The bag surface is flat and smooth, with rich patterns and bright colors, and it also has anti-counterfeiting functions. In addition, PE heavy-duty packaging bags have excellent sealing, moisture resistance, waterproofness and anti-fouling properties, making them suitable for open-air stacking and easy transportation and storage.
Applicable scenarios
PE heavy-duty packaging bags are often used to package granular or powdered fertilizers, and have good chemical corrosion resistance, moisture resistance and flexibility. This packaging method is not only suitable for fertilizers, but also widely used in other scenarios that require efficient and low-cost packaging.
Materials and characteristics
The main material of PE heavy-duty packaging bags is polyethylene (PE). According to the polymerization method and molecular structure of polyethylene, PE bags can be divided into low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE) and high-density polyethylene (HDPE)
3. These materials have different characteristics and application scenarios
LDPE: It has good flexibility, transparency and heat sealing properties, and is often used to package food, medicine, daily necessities, etc.
• LLDPE: It has high strength and toughness, and is suitable for packaging heavy objects and industrial products.
• HDPE: It has high hardness and wear resistance, and is often used to package building materials and chemical products.
Environmental protection and cost-effectiveness
PE heavy-duty packaging bags are easy to recycle and are beneficial to ecological protection. With the application of new materials, the film thickness is reduced and the strength is enhanced, and the comprehensive packaging cost is better than traditional packaging forms. This environmental protection feature makes PE heavy-duty packaging bags have significant advantages in sustainable development.
