Silver centre-spout pouch

The silver centre-spout pouch offers resealable packaging with an opaque surface for liquid products. The central spout clearly defines the point of filling and dispensing, while the silver exterior, together with the chosen structure, shapes the protection of the product. The pack can be designed in a stand-up or flat pouch format. This solution deserves attention if aroma protection, reduced light exposure and convenient use are all important for the liquid.

An opaque exterior for liquid products

In the silver pack the contents are not visible from the outside. The opaque surface can be an advantage for light-sensitive products, while we choose the required aroma and moisture barrier based on the entire material structure. The composition of the specific liquid, its storage environment and the filling method determine the protection required. Different versions can be agreed for different packaging needs, so the technical requirements must be defined in parallel with choosing the appearance.

A centrally placed cap

The spout positioned on the axis of the pouch can be matched to both manual and machine filling. When choosing the opening and the cap, we examine the fit of the filling head, the flow properties of the product and pourability during use. The cap serves to reseal the opened pack, so its ease of use is an important part of the customer experience. It is worth trying the pouch both fully and partly filled, to see how it is held, the shape of the pack and how dispensing works in practice.

Pack size and format

In the 0.2–1 litre range, we agree the right size for the desired fill. The stand-up format provides a starting point for upright placement, while the flat version can be fitted to different storage and outer packaging arrangements. The fill allowance, the space required by the spout and the final closure must be handled as part of the sizing. As the fill level cannot be followed by eye through the silver surface, accurate dosing must be ensured by the filling process, and the net quantity must be stated clearly in the product labelling. The planned shelf space can be assessed accurately with a filled pouch.

Requirements of the filling process

For hot filling, a vacuum process or other specific technological requirements, we first agree a suitable material and closure. The chosen pouch must be compatible with both the liquid and the entire temperature process. During a trial fill, it is worth checking the sealing of the spout and the cap, the deformation of the pouch and ease of handling. Testing of the finished pack must also cover the planned storage and transport conditions, so that the material choice is linked to real use.

For a quote on a silver centre-spout pouch, please send us the product name, the required capacity and the filling method. By telling us the storage environment and the desired pack format, you give us a more precise starting point. As a result of our discussion, we match the protective functions, the central spout and the proportions of the pack to the same liquid.
