For global apparel wholesalers, hat brands and cross-border distributors looking for economical and high-volume packaging, custom PE flat open top bags remain one of the most practical packaging choices for mass shipments. As a professional plastic packaging manufacturer, we provide fully customizable flat poly bags optimized for manual packing and automatic packaging lines, supporting large-volume export orders for apparel, headwear, hardware and general merchandise.
PE flat open top bags feature a simple yet reliable construction: fully open top and one side permanently heat-sealed at the bottom. Unlike reclosable bone bags with zipper strips, flat bags adopt an open-mouth design, allowing fast product loading. After items are placed inside, clients can seal the opening via heat sealer, adhesive tape or other closure methods based on their packing workflow. This flexible structure makes flat bags perfectly suited for factories with high-speed automatic packaging lines, greatly improving packing efficiency for bulk production.
We use virgin LDPE raw material as standard, with optional food-grade PE and GRS recycled PE for buyers with eco-friendly requirements. The blown film process delivers consistent film thickness, good tensile strength and outstanding puncture resistance. The bottom heat seal is our core craftsmanship. During production, the bottom edge is continuously heat-fused under stable temperature and pressure. This eliminates weak sealing points, preventing tearing or leakage during long ocean transit, pallet stacking and repeated handling in overseas warehouses.
Customization options cover full dimensions, film thickness and surface printing. Buyers can specify exact width and length to fit baseball caps, bucket hats, folded t-shirts, socks, hardware parts and gift goods. Gravure printing supports brand logos, product descriptions, batch codes and mandatory warning marks required by US and EU import regulations. Clear transparent film is our standard option for direct product display. We can also adjust film formula for milky white or custom tinted bags upon request.
Our complete flat bag production workflow runs from PE pellet feeding, film blowing, roll printing, continuous bag making, bottom heat sealing, cutting to offline QC sampling. During quality inspection, our QC team focuses on bottom seal strength, film thickness uniformity, surface cleanliness and cutting neatness. We carry out tensile tests on sealed bottoms to verify the bag can bear weight without rupture. Any bags with weak seal, pinholes or scratches will be filtered out before packing.
This series of flat bags serves multiple packaging purposes. For hat exporters, they work as primary inner packaging to keep hats dust-free and avoid surface scratches before being packed into export cartons. Garment factories widely use flat bags for folded clothing bulk packing. Hardware, toys and daily goods suppliers select flat bags for component protection and unit separation. Whether you arrange small trial orders or full-container bulk shipments, our production schedule can adapt to your order volume.
Cost efficiency and stable lead time are the biggest advantages of PE flat bags. Thanks to simple structure and mature production technology, flat bags deliver lower unit cost compared with zipper or bone bags, which helps buyers reduce overall packaging expenditure for large export consignments. We are familiar with packaging compliance standards for North America, Europe, Southeast Asia and Australia. We can supply test reports and supporting documents to smooth customs clearance.
We offer free sample service so buyers can test material quality, bottom seal performance and printing effect before confirming mass production. If you are sourcing bulk open-top PE flat bags for hat, apparel or general export products, share your size, thickness and artwork requirements. Our packaging team will analyze your packing workflow and provide competitive quotation with professional technical advice.
