Paper stand-up press-to-close pouch with window

The paper stand-up press-to-close pouch with window complements its brown paper exterior with a transparent viewing window. The pack keeps the understated look of the paper surface while showing part of the contents. The stand-up format is an advantage for upright display, and the press-to-close zip for repeated use. This version is made with an aroma barrier and a medium moisture barrier; chosen for the right product, the window and the barrier properties together support the pack.

A view alongside the paper surface

The window helps show the character, colour or grain size of the packed product without the whole pouch having to be transparent. The fill level should be planned so that the contents are actually visible in the viewing area. The label position must also be matched to this: the important part of the window should stay clear, and the product name should be legible with the pack standing upright. It is advisable to examine the visual effect with the actual fill before the production decision.

Aroma barrier and grease-resistant design

The pouch material is also designed to reduce grease showing through the paper, so it can be considered for packing oily seeds and products with a suitably chosen fat content. Because of the medium moisture barrier, the needs of fills that are particularly sensitive to moisture must be checked separately. The composition of the product, the ambient humidity and storage together influence the choice. We assess the suitability of the window version together with the whole structure, the fill and the seal.

A labelling surface for your own branding

This paper pouch with window cannot be printed directly; its own-brand look can be created by labelling. When designing the label, it is advisable to choose colours that suit the brown base and easily legible lettering. With several product variants, the label can differentiate the packs while using a common pouch size, if the fill volume allows this. Labels are best applied to a flat, easily accessible area, and label adhesion should be checked under the actual storage conditions. The label size must also be matched to the folds of the pouch, so that the text stays on the paper surface and does not end up under the gusset after filling.

Opening and resealing

A tear notch on the pouch helps open the top, and the press-to-close zip is used to close it again after opening. The available sizes include 120 × 150/30, 150 × 200/35 and 180 × 250/40 mm versions. The fill must leave the opening and resealing area free, so we choose the size based on the volume and the required space at the top. The gusset gives the pack its shape when filled; a trial pack shows both the stability and how the product looks in the window.
