[Chinese Packaging Network News] According to experts from Chinese Packaging Network, most courier bags currently available on the market are made from recyclable PE (polyethylene) materials. These bags are lightweight, cost-effective, and ideal for everyday use. However, there are also higher-quality courier bags on the market that come at a higher price but offer better durability and protection. When shopping for courier bags, consumers should pay attention to several key factors to ensure the safety of their packages during transit.
First, the material's toughness is crucial. Courier bags made entirely from PE or new raw materials tend to be more durable and resistant to wear, ensuring that your products remain safe during shipping.
Second, the thickness of the bag plays an important role. Since PE and new materials have a fixed density, the thickness depends on the size and weight of the items you're shipping. Generally, a thickness between 11-15 microns is sufficient for most standard deliveries. Thicker bags provide better protection but come with a higher cost, so it's best to choose based on the weight and fragility of your items.
Third, the edge strength of the bag is equally important. Many bags fail due to poor sealing at the edges, often caused by impurities in the material or substandard cutting techniques. It’s essential to choose a courier bag with strong, stable edges that can withstand the pressure of shipping without tearing.
Fourth, the adhesive quality of the sealing tape is vital. High-quality glue ensures a secure and tamper-resistant seal. The right type of adhesive should match the material of the bag, and water-based glues are often preferred for their strong adhesion and effectiveness.
Fifth, the bag should stick well to the courier list or label. If the material is not pure or contains impurities, it may not adhere properly, leading to issues during delivery. Choosing bags made entirely from PE or new materials ensures better adhesion and reliability.
Lastly, opacity is another important feature. A non-transparent courier bag helps maintain the privacy of the contents, which is especially important for sensitive or personal items.
Experts from Chinese Packaging Network remind users that while basic, affordable courier bags are suitable for lighter items like clothing, they may not be ideal for heavier or more delicate products. To enhance security, it's recommended to pair these bags with strong packing tape. If you're not using tape, opt for thicker or new material bags to ensure the safety of your package throughout the delivery process.
