根拠の範囲

Side-gusset dimensions, folds, print zones, closure placement, sealing and filling-site handover.

適用範囲と限界

The sources do not prescribe gusset depth, usable volume or closure position. These require the actual product, drawing, converted sample and filling equipment.

要点

Finished volume depends on all dimensions and the filled product.
Seal evaluation must reflect folded-layer transitions and process conditions.
An empty pouch is not sufficient evidence of final geometry or line fit.

よくある質問

What products suit side gusset bags?

Coffee, tea, dried fruit, nuts, granola, powder mixes, bulk dry food and specialty products.

Can side gusset bags have a coffee valve?

Yes. One-way degassing valves are commonly used on side gusset coffee bags.
