USA • Constantia Flexibles has increased its position in the stick-pack market by acquiring a new narrow web and short-run slitter with an enhanced laser perforation unit.
Constantia Flexibles’ laser-perforated stick packs are comprised of PET/AL/PE or paper/AL/PE to protect the contents against moisture, oxygen and light
According to Constantia, the sophisticated laser technology is a factor in the product’s popularity because it allows for a range of opening features to be incorporated into primary packaging material–with a reduced effect on a customer’s preferred packaging process.
The company hopes the investment will allow the converter to accommodate greater customer demand for its laser-perforated stick packs, as well as provide more insurance against production delays or maintenance downtime with related equipment.
Constantia Flexibles’ laser-perforated stick packs are comprised of PET/AL/PE or paper/AL/PE to protect the contents against moisture, oxygen and light. A laser perforation below the seal ensures easy opening of the stick. The PET or paper in the vicinity of the laser seam is partially removed while the aluminum layer remains intact, thereby ensuring the stick pack’s impermeability.
Constantia claims that some of the benefits of these stick packs include:
Pre-determined breaking point for convenient, easy-to-open packaging;
Integrated perforation of packaging with no necessary equipment modifications;
Flexible perforation-layout to accommodate varying customer needs;
Child-resistant options and capabilities;
Both printed and unprinted offerings;
Package remains impermeable to oxygen and moisture; and
Significantly lower use of material compared with sachets, equaling a cost savings of up to 40% on square sachets and associated costs such as reel storage, worn out parts, space reduction in storage, etc.
