The weakening of the material is designed to make opening the package easier. Our customers mainly use the following foils and flexible films:
Non-laminated foils such as PET, APET, PE, PLA, OPP, and PA, and composite foils such as PET/PE, PET/Alu/PE, and PET/Paper/Alu/PE ,kraft paper and special materials from research and development.
In these easy-opening solutions, the material can be scored in the web direction, cross web direction or in a free form. Not all foils are the same. Different foodstuffs packagings have different barrier film, which are derived from the foodstuff in question and its intended use of the packaging.
The depth of material weakening is controlled by the COPTICS software and can be set with immense precision. This means that the barrier properties are not adversely affected or knowingly changed by the laser score processing.
Laser scoring makes packages for chips, nuts, candy or other snacks easily accessible, and various options for closures improve the consumer experience of products through multiple servings.
Coptics laser scoring machine offer a special concept: they weaken foil webs with the maximum producticity and quantity. Stand-alone roll-to-roll laser machine are interim solutions. Depending on the application and scoring method, all the usual material widths can be worked.
To produce an easy-opened solutions, the materail can be scored as follows:
1) Web direction
2) Cross web diretion
3) Contour scoring
• Proven for easy open, re-sealable, retort & pourable packaging
• Excellent for microwave steam release features
• Controlled score depth & location
• Precise score lines or shapes
• Straight lines and/or contoured features
• Capabilities for machine and transverse direction
