Quoting from structure and gauge without roll geometry
Packaging format
Roll Stock
Roll stock comes in many constructions. Some applications need sophisticated multi-layer barrier laminations. Others perform best with a straightforward surface-printed polyethylene film. Packaging HQ starts with the application and line requirements.
PROJECT FOCUSRoll stock is defined by a full specification.
Web dimensions, film layers, print, seals, and roll requirements are developed around the application and filling line.
What the specification must resolve
What to confirm before production.
A complete roll-stock specification ties the structure and print to the converting or filling line. It covers web width, repeat, unwind, core, maximum roll dimensions, splice rules, registration, friction, stiffness, seal response and barrier.
Key considerations
- Web width, repeat, unwind and core
- HFFS, VFFS, stick-pack, sachet or other equipment
- Seal initiation, hot tack, COF and stiffness
- Barrier, gauge, print and lamination needs
Common applications
- Pillow bags and flow wrap
- Stick packs and sachets
- Frozen foods and novelties
- Forming and lidding applications
Where projects go off track
Confirm these details early.
Changing materials without comparing COF, curl, stiffness and hot tack
Approving artwork before repeat, eye mark and unwind are confirmed
01Product, fill and performance target
02Filling line, dimensions and material inputs
03Samples, trials, graphics and final approval
A common question
Can Packaging HQ match an existing roll-stock specification?
A current specification, roll label, sample and line information provide the best starting point. The review should cover functional and roll requirements along with the named material layers.
