what is plastic pouch?
Plastic Pouch bag packaging is a flexible packaging product made from barrier film, foil, and spout and cap fitments that supports flowable liquid products. Pouches are designed with the flexible needs of the consumer in mind, as there are flexible sizing options to fit any product.
Why people choose plastic pouch?
A product packed in plastics pouch has several requirements, such as:
- Good combination of mechanical properties,for running on printing & packaging machines.
- Controlled barrier to vapours and gases, for desired product shelf life.
- Sealability of pouches to keep the packaged product intact.
- Printability for attractive graphics and disseminating information about the product.
- Aesthetic appeal.
Each of the layers mentioned in the laminated structure serves one or the other of the five functions listed above.
If used in top layer, PE with proper treatment (corona or primer coating) is used for printing, in addition to providing barrier to moisture.
Alternatively PET on top offers a much better printable surface.
MetPET gives shine, opacity, cuts out light reaching the packaged product and enhances barrier to oxygen ingress.
The bottom PE layer is used for sealability.
