The non-woven shopping bags found in supermarkets are considered environmentally friendly alternatives to traditional shopping bags, and they are very useful in various supermarkets. More and more people are choosing these non-woven shopping bags to carry their items. So, can non-woven shopping bags be degraded? What are the types of supermarket shopping bags? Supermarket non-woven shopping bags can be degraded. Non-woven shopping bags are non-textile materials made of plastic; many people assume that since it’s called “fabric,” it must be a natural material, but this is a misconception. The common raw materials for non-woven fabrics are polypropylene (abbreviated as PP, commonly known as polypropylene fiber) or polyethylene terephthalate (abbreviated as PET, commonly known as polyester), while the raw material for plastic bags is polyethylene. Although these two materials have similar names, their chemical structures differ greatly. The chemical molecular structure of polyethylene possesses considerable stability and is extremely difficult to degrade; as a result, plastic bags take 300 years to completely break down. In contrast, the chemical structure of polypropylene is less stable, and its molecular chains can break easily, allowing for effective degradation; it then enters the next stage of the environmental cycle in a non-toxic form. A non-woven shopping bag can be completely decomposed within 90 days. Essentially, polypropylene (PP) is a typical type of plastic, and its environmental pollution level after disposal is only 10% that of plastic bags. Supermarket non-woven shopping bags have the following features: Non-woven bags, commonly known as clothless bags, represent a new generation of eco-friendly materials. They possess properties such as moisture resistance, breathability, flexibility, light weight, non-flammability, easy biodegradability, being non-toxic and non-irritating, a wide range of colors, low cost, and reusability. Advantages of supermarket non-woven shopping bags: 1. Air permeability 2. Filterability 3. Thermal insulation 4. Water absorption 5. Water resistance 6. Elasticity 7. Doesn’t get messy 8. Good feel and soft texture 9. Light weight 10. Elastic and capable of returning to its original shape 11. No orientation issues like with woven fabrics 12. Higher productivity and faster production speed compared to woven fabrics 13. Lower cost, allowing for mass production, and so on. Disadvantages of supermarket non-woven shopping bags: 1. They have lower strength and durability compared to woven fabrics. 2. They cannot be washed like other types of fabrics. 3. The fibers are arranged in a specific direction, which makes them prone to cracking at right angles, etc. Therefore, improvements in the production method focus mainly on enhancements to prevent splitting. In fact, supermarket non-woven shopping bags are biodegradable, and this is why they have become so popular in recent years. The editor also discussed the advantages and disadvantages of non-woven shopping bags; therefore, by paying attention to such safety tips from websites like Baibai Safety Network, one can gain an understanding of these aspects.
