Best Practices of Shipping Bags for Shipping

Red Mail Bag

Proper Packaging
Ensure that products are packed snugly within the poly bag to minimize movement during transit. For fragile items, consider using bubble poly mailers or adding protective layers like bubble wrap or packing paper inside the bag.

 

Secure Sealing
Make sure the bag is securely sealed to prevent tampering and protect the contents. Self-sealing strips should be pressed firmly to adhere properly, and additional sealing tape can be used for extra security if needed.

 

Labeling and Documentation
Labels should be applied smoothly to avoid peeling off during transit. Choose a poly bag that allows for easy label application, and make sure the barcode and shipping information are clearly visible. For international shipments, attach necessary documentation such as customs forms in a clear poly pouch.

 

Consider Seasonal Factors
Take weather conditions into account when shipping products. Poly bags protect against moisture, but extreme temperatures can still affect certain products. Use additional insulation for sensitive items during hot or cold weather.

 

Optimize for Shipping Carriers
Each carrier may have different guidelines regarding size, weight, and packaging. Review carrier requirements to ensure your poly bags meet dimensional criteria to avoid unexpected fees or complications.

 

Understand the Types of Courier Bags

Plastic Courier Bags

These are lightweight, water-resistant, and durable. They're ideal for shipping non-fragile items like clothes, documents, and small electronics. Plastic courier bags also offer tamper-evident options to ensure the security of the shipment.

cPaper Courier Bags

With sustainability becoming a priority for many businesses, paper courier bags are growing in popularity. They are eco-friendly, biodegradable, and recyclable, making them a great choice for companies looking to reduce their environmental footprint.

Bubble Lined Courier Bags

If you're shipping fragile items or products that require extra protection, bubble-lined courier bags are an excellent option. The internal cushioning helps absorb shocks and protects the contents from damage during transit.

Tamper-Proof Courier Bags

These are ideal for businesses that need to ensure the security of their shipments. Tamper-proof bags come with special seals that make it evident if the package has been opened before delivery. This feature is particularly useful for shipping confidential documents, high-value products, or sensitive items.

 

Production Procedure
 

Raw material selection
We rigorously select high-quality raw materials such as PE, PP, PA, and PLA to ensure our products possess excellent transparency, toughness, and environmental performance. All raw materials meet food-grade or environmental standards, providing customers with safe and reliable packaging solutions.

 

Design drawings
Based on customer needs, our design team provides professional drawing solutions, including bag design, size specifications, thickness selection and printing effects, to ensure that the product is beautiful and practical and in line with the customer's brand positioning.

 

Blown Film
Using advanced film blowing machines, through precise temperature control and ratio technology, the film thickness is uniform, the tensile strength is high, and the surface is smooth, providing high-quality substrate for subsequent printing and bag making.

 

Packaging bag printing
We are equipped with high-speed color printing machines that support gravure printing and flexographic printing, up to 12 colors, with clear and bright patterns and high color reproduction, helping customers to better display their brands.

 

Bag Making
Through fully automatic bag-making equipment, we can accurately seal and cut the bags according to the bag shapes required by customers (such as ziplock bags, express bags, shopping bags, etc.), ensuring that the bags are strong and durable, with neat and beautiful appearance.

 

Quality Inspection
From tension, sealing, thickness, transparency to printing effect, we have multiple testing procedures to ensure that each batch of products meets international quality standards and the defective rate is reduced to a minimum.

 

Packaging and warehousing
Finished products are packaged in standard cartons or custom packaging, in batches with precise quantities to ensure the bags are not contaminated or damaged during transportation. Final inspection, including appearance, function, and quantity verification, is carried out before shipment to ensure that each batch meets customer requirements before being stored for shipment.

 

Loading and shipping
Finished products are loaded into containers through reasonable stacking to make full use of space and prevent squeezing and deformation. They are then arranged for sea, air or land transportation according to the transportation method specified by the customer to ensure safe and timely delivery.
