Constantia Flexibles is strengthening its position in the stick pack market by acquiring new state-of-the-art equipment, including a narrow web and short run slitter with an enhanced laser perforation unit.
The infrastructure investment will allow Constantia Flexibles to accommodate greater customer demand for its laser-perforated stick packs, as well as provide redundancy to insure against production delays or maintenance downtime with related equipment.
The sophisticated laser technology is a key factor in the product’s popularity to date; laser perforation allows for a wide range of opening features to be incorporated into primary packaging material with no effect on a customer’s preferred packaging process.
Constantia Flexibles’ laser-perforated stick packs are comprised of PET/AL/PE or even paper/AL/PE to protect the contents against moisture, oxygen and light. 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 remains impermeable
Stick packs result in a significantly lower use of material compared with sachets, according to Constantia flexibles, equaling a cost savings of up to 40 percent on square sachets and associated costs such as reel storage, worn out parts, space reduction in storage, etc.
