Judging shrink only from a lab sample
Packaging format
Shrink Bundling Film
Bundling film should deliver the required holding force, shrink window, optics and toughness without creating unnecessary material. Tunnel conditions and pack geometry are important inputs.
PROJECT FOCUSHolding force and the tunnel window determine bundle performance.
Format, materials, print, and finish are developed around the product, production requirements, distribution, and brand.
What the specification must resolve
What to confirm before production.
The film must shrink around the pack geometry without unacceptable distortion, openings or damage. Gauge, shrink curve, toughness, print and tunnel temperature and dwell should be balanced for the actual bundle.
Key considerations
- Bundle geometry and holding force
- Tunnel temperature and dwell
- Optics, print and registration
- Puncture and tear resistance
Common applications
- Beverage multipacks
- Consumer goods
- Food products
- Retail bundles
Where projects go off track
Confirm these details early.
Using excess gauge instead of solving pack or tunnel conditions
Ignoring openings and stress around corners or handles
01Product, fill and performance target
02Filling line, dimensions and material inputs
03Samples, trials, graphics and final approval
A common question
Can printed bundling film run like unprinted film?
Print can change friction, heat response and registration requirements. The printed web should be qualified on the intended bundler and tunnel.
