To choose a good PE bag, consider the following:
Material: PE bags are made of polyethylene (PE), which is safe, non-toxic, odorless, and highly transparent, making it ideal for food storage. Ensure the material is pure and free of harmful chemicals.
Thickness: PE bag thickness is typically measured in "threads." Lightweight items like small accessories can be handled with thinner bags. Heavy items like dry goods and tools require thicker bags with double-sided 16-thread, 20-thread, or even 30-thread fabrics for durability and protection.
Size: Choose the size of your PE bag based on the size of your items. Mini bags are ideal for small jewelry, everyday bags are suitable for stationery and snacks, document bags are suitable for A4 documents and important documents, and large storage bags are ideal for shoes and larger electronics.
Quality Inspection:
Smoothness and Transparency: A high-quality PE bag should have a smooth, flat surface without noticeable wrinkles and high transparency, allowing the contents to be clearly seen.
Color Uniformity: The color should be uniform and consistent, without color variations or spots.
Impurities and Bubbles: Check the bag for impurities, bubbles, and other defects.
Zipper Quality: For PE zipper bags, the zipper should be smooth and easy to open, without sticking or breaking.
Sealing Performance: The bag should not leak after sealing.
Odor: A qualified PE bag should have no noticeable odor. If a pungent odor is detected, it may indicate the use of inferior raw materials or additives.
Brand Recognition: Choose products from reputable brands, as these brands generally prioritize product quality and safety, reducing the risk of use.
