PE Side Gusset Bags
Product Description
PE Side Gusset Bags are LDPE pouches with folded side gussets that expand outward to give the bag volume rather than just flat thickness. The gusset ratio is 1:3, meaning the sides open up to three times the flat dimension, turning a narrow sleeve into a bag that stands and holds boxed goods, parts and packaged items. Clarity is about 92 percent, so the contents remain visible, and the seal system supports both heat-sealing and self-adhesive closure depending on how the customer runs their packing line. Sizes run from 15x20 cm to 40x60 cm at 0.06-0.12 mm, food-grade under GB 4806.7, with an optional 60 percent recycled content blend. The bag solves the common problem of flat film that cannot hold bulky, three-dimensional items, and does so without sacrificing the clear visibility that retail and food buyers need on a packed shelf.
A gusseted bag only works if the side folds open evenly and stay that way under packing-line speed; crooked or collapsed folds cause jams and rejected bags. Our integrated bag-making lines control the 1:3 gusset fold geometry so the expansion ratio is consistent across the run, which lets an automated packer feed, fill and seal the bag without operator correction. Offering both heat-seal and self-adhesive closure on the same gusset construction is a production-consistency point, not a menu: it means a customer can switch between a sealing line and a hand-pack line without redesigning the bag geometry. For a brand that packs goods in volume, the value is a gusset that reliably expands to the rated 1:3 and seals the same way every time, reducing line stops and the variability that comes from sourcing gusseted film in small lots.

Applications
Boxed and Three-Dimensional Retail Packaging.
The 1:3 gusset lets the bag open to fit boxed goods and odd-shaped items that flat sleeves cannot hold, while 92% clarity keeps product visible on shelf.
Automated Packing and Filling Lines.
Consistent gusset geometry and dual heat-seal/self-adhesive closure let the bag run on automatic equipment without frequent operator adjustment.
Food and Ready-to-Eat Packaging.
Food-grade GB 4806.7 compliance and the standing gusset form make the bag suitable for packaging bakery, produce and prepared food that needs depth.
Customization
Sizing from 15x20 to 40x60 cm, gauge 0.06-0.12 mm, gusset width, heat-seal or self-adhesive closure selection, printed branding, optional 60% recycled blend, and production from drawings or samples are offered. OEM and mixed specs within one MOQ are supported.
Packaging & Transportation
Bags are packed in export carton boxes. Trade terms are negotiable; transit-damaged items are replaced, and third-party inspection is accepted.
FAQ
Q1. How much volume does the side gusset add?
A. The gusset is built to a 1:3 expansion ratio, so the side folds open to three times the flat width to hold three-dimensional contents.
Q2. Can I choose between heat-seal and self-adhesive closure?
A. Yes, the same gusset construction supports both heat-sealing and self-adhesive closure to match your packing line.
Q3. What is the MOQ and lead time?
A. MOQ is 50,000 pcs; customized lead time is 15 days, and mixed colors or models are allowed within that MOQ.
