As a common packaging material in daily life and industrial production, PE bags are of various types, and the most common ones are heavy-duty PE bags and ordinary PE bags. Although both bags are made of polyethylene (PE), there are significant differences in material, thickness, strength and application areas. Understanding these differences not only helps us choose the right packaging material, but also better protects and transports items. Therefore, this article will explore the differences between heavy-duty PE bags and ordinary PE bags in detail.
1. Differences in material and thickness
Heavy-duty PE bags: Heavy-duty PE bags use thicker polyethylene materials, usually with a thickness of 0.1 mm to 0.2 mm. Due to the thickening of the material, heavy-duty PE bags have stronger load-bearing capacity and durability, and can effectively carry heavier items or transport for a long time.
Ordinary PE bags: Ordinary PE bags are relatively thin, generally between 0.02 mm and 0.1 mm, and are suitable for daily packaging of lightweight items. They have lower strength and durability, and are more suitable for packaging products that do not require too high strength.
2. Strength and durability
Heavy-duty PE bags: Due to their thicker material, heavy-duty PE bags have higher tensile strength and puncture resistance, can effectively withstand greater pressure and weight, and are not easy to break or damage. They are often used to package heavy items, such as building materials, chemicals, bulk commodities, etc.
Ordinary PE bags: Ordinary PE bags have relatively low tensile strength and puncture resistance, so they are not suitable for packaging heavy items. They are mainly used for lightweight packaging in daily life, such as food, clothing, stationery, etc.
3. Application areas
Heavy-duty PE bags: Heavy-duty PE bags are widely used in industries such as industry, chemical industry, construction, and agriculture. They are often used for packaging bulk goods, such as cement, sand, fertilizers, granular materials and other heavy objects, which can ensure the safety of items during transportation.
Ordinary PE bags: Ordinary PE bags are mainly used for packaging light items, such as clothing, food, stationery, daily groceries, etc. They are usually used in the retail industry or for personal use by consumers.
4. Production process and cost
Heavy-duty PE bags: The materials and processes required to produce heavy-duty PE bags are relatively complex, so their production costs are relatively high. Thicker PE films require higher processing precision and stronger equipment support, and the energy consumption in the manufacturing process is high.
Ordinary PE bags: The process for producing ordinary PE bags is relatively simple, using thinner polyethylene films, and the manufacturing cost is low. Since no complex process is required, ordinary PE bags are also cheaper in the market.
5. Environmental protection and recycling
Heavy-duty PE bags: Due to their large thickness, heavy-duty PE bags are more recyclable. Many heavy-duty PE bags use recyclable polyethylene materials, which can effectively reduce resource waste. However, their use is often accompanied by greater environmental impact, especially when used on a large scale.
Ordinary PE bags: Ordinary PE bags have relatively serious environmental problems because they are usually widely used and quickly discarded, causing plastic pollution. Although these bags can also be recycled, they are difficult to recycle and reuse because they are thin and easy to break.
In practical applications, it is crucial to choose the right type of PE bag according to different packaging needs. Our FFS Heavy-duty PE Tubular bags offer excellent endurance and good thickness uniformity. In an integrated solution known as a form-fill-seal (FFS) system, the bag is cut and shaped from a continuous reel, then filled and sealed before becoming a final pack. The FFS system can increase filling operation efficiency while lowering labor expenses. The FFS fully automated packaging production line is designed for this kind of bag. The bag is comprised of a single substance and may be recycled right away.
