The durability of transparent plastic bags depends on multiple factors, including material type, thickness, manufacturing process, and usage environment. Here are some key points to help you understand the durability of transparent plastic bags:
1. Material type
Polyethylene (PE): A common transparent plastic bag material with good flexibility and tear resistance, but may be easily damaged under sharp objects or heavy pressure.
Polypropylene (PP): Harder than PE, higher transparency, better tear resistance, but slightly less flexible.
2. Thickness
Thin bags (such as less than 0.01mm): Suitable for lightweight items, but easy to tear or perforate.
Thick bags (such as more than 0.02mm): Suitable for heavier or sharp items, with significantly improved durability.
3. Manufacturing process
Ordinary bags: Simple seams and edge treatments, easy to crack at stress points.
Reinforced bags: Seams and edges are reinforced for better durability.
4. Usage environment
Temperature: High temperatures may soften plastic bags, and low temperatures may make them brittle.
Humidity: A humid environment may affect the strength of the bag.
Friction and impact: Frequent friction or contact with sharp objects will increase the risk of breakage.
5. Usage
Lightweight items: Transparent plastic bags usually protect lightweight items well.
Heavy items: If the bag is too thin or the material strength is insufficient, it may break.
Sharp items: Sharp edges can easily pierce the bag, so it is recommended to use thickened or reinforced bags.
6. Common problems
Tears: The edges or seams of the bag are prone to tearing, especially thin bags.
Punctures: Sharp objects can easily pierce the bag.
Aging: The bag may become brittle after being exposed to sunlight or high temperature for a long time.
Choosing the right material and thickness according to specific needs can effectively improve the durability of the bag.
