A plastic pouch is one of the most common forms of packaging and is great for containing and transporting goods such as foods, produce, powders, liquids and chemicals.
Plastic pouches can be made from a variety of plastics films with Polyethylene being the most common ingredient. A typical pouch is made of multiple plastic layers including PE, PET, laminates and metal foils. Pouches can come in a variety of shapes and sizes such as:
- Stand up pouches
- Retort pouches
- 3 side pouches
- Spouted pouches
- Zipper pouches
- Quad seal pouches
- Fin seal pouches
Most plastic pouches are heat-sealed while some are bonded with adhesives.
While you may have already known this, what you may not know is how important the choice of punches and punch attachments is to your pouch operation.
As more consumer products move to pouch packaging, pouch manufacturers need a reliable, close clearance punch that delivers precise, high-quality edges on a wide range of materials while keeping the cost of operation low.
While zero-clearance units deliver exceptional edge quality, the reality now is that many close-tolerance punches can deliver the same, if not better edge quality depending on the material and thickness.
When evaluating your operation, keep in mind that traditional zero-clearance punch attachments have a higher cost of manufacturing due to expensive punches and dies that require frequent downtime for sharpening or replacement. Of course, zero-clearance attachments will always have their place in the industry when near-zero tolerances are necessary, like in medical or pharmaceutical packaging.
That said, there are products, such as Pearl’s UltraFlex HD, that offer pouch manufacturers an innovative, lower-cost solution since interchangeable punch and die plates eliminate the need to replace the entire unit for maintenance or when different profiles are desired.
