Layflat Poly Mailers
Layflat poly mailer bags are basically the industry standard. If you've ever ordered something from a popular e-commerce company, you've probably received it in a layflat poly mailer. It's a flat plastic bag that can hold a wide array of items, is good for items that don't need a lot of cushioning, and can be easily affixed with stamps and sealed with a self-adhesive strip.

 

Clear View Poly Mailers
Clear view poly mailers are a solid choice for shipping print materials like catalogs, brochures, and magazines. They're completely transparent (hence the clear view) on one side with an opaque backside that's perfect for postage, labels, and other shipping information.

 

Bubble-Lined Poly Mailers
For fragile goods that don't necessarily need a fully packaged box, bubble-lined poly mailers offer extra cushioning and added protection. They're a low-cost way to send small, delicate items to customers and are usually self-sealable.

 

Expansion Poly Mailers
Expansion poly mailers come with an expandable, durable seam along the side that makes it easier and more efficient to ship bulky items. These work well for shipping large items like jackets, sweatshirts, books or binders.

 

Returnable Poly Mailers
As we all know, product returns are one of the many inherent costs of doing business online. Returnable poly mailers are a popular way to ship products while planning ahead for potential returns (and are often included in initial shipments). They have two self-seal adhesive closures, offering customers the ability to conveniently return an order directly to your receiving address.

 

Recycled Poly Mailers
If you're trying to build a more eco-friendly, sustainable business, 100% recycled poly mailer bags are made with a mixture of post-industrial and post-consumer materials and have a significantly lower carbon footprint than their virgin counterparts.

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
