Introduction
Air trapped inside a garment zipper bag can make filled packages appear inflated, create unstable stacks and reduce the number of packs that fit comfortably into a carton. Small ventilation holes can help air escape during packing and stacking.
Their position should not be chosen casually. Holes placed too close to a seal, underneath a thick garment fold or through important printing can create avoidable quality and presentation problems.
For importers, apparel wholesalers, distributors and clothing brands, vent-hole quantity, diameter and position should be shown on the approved bag drawing and verified with the actual folded product.
Start With the Filled Garment Position
An empty bag does not show where the garment will sit after packing. Before selecting the hole position, load the largest or thickest intended product using the approved folding method.
Review where the garment creates pressure against the film. Waistbands, cuffs, buttons, zippers and stacked fabric edges can cover a hole or press directly against it.
A practical position should:
- Remain clear of the zipper track.
- Avoid the thickest part of the folded garment.
- Leave adequate distance from side and bottom seals.
- Avoid important printed graphics and product information.
- Remain accessible when filled bags are stacked.
- Support the intended packing and carton-loading process.
There is no universal distance suitable for every bag. Confirm the position according to bag size, seal width, product layout and manufacturing capability.
Keep Holes Clear of Heat-Sealed Areas
Ventilation holes and heat seals perform different functions. A hole should not overlap the functional seal area or create an unclear inspection boundary near the seal edge.
Use a dimensioned drawing to define each hole from fixed bag edges. Avoid instructions such as “near the bottom” without measurement points and tolerances.
