Kanıt kapsamı

Quad-seal versus flat-bottom identification, filled-sample comparison, seal review and quotation controls.

Kapsam ve sınırlamalar

Standards do not define one format as superior. Exact geometry, dimensions, standing stability and carton fit depend on drawings and converted filled samples.

Temel sonuçlar

Quad seal and flat bottom require distinct geometry records.
Seal-strength and visual methods answer different questions.
Format alternatives need separate drawings, samples and approval.

Sıkça Sorulan Sorular

Is a quad seal pouch the same as a flat bottom pouch?

No. A quad seal pouch uses flexible side gussets, four vertical corner seals and a conventional bottom seal. A flat bottom pouch has a separate bottom panel and different corner geometry.

Which format has better shelf presentation?

Neither is automatically better. Compare fill weight, product density, filled shape, display panels and the intended retail shelf.

Which format should be used for coffee or pet food?

Either format may be suitable. The decision should consider fill weight, product particles, closure, laminate, filling path and a representative filled sample.
