CPP cast polypropylene film
CPP cast polypropylene film — reliable sealing, stable machine run and flexible structures
CPP cast polypropylene film is the standard sealant layer in laminates for VFFS, HFFS and flow-wrap applications. It provides low sealing initiation temperature (SIT), high hot-tack, excellent puncture resistance and flexibility, allowing packaging to start faster, maintain seal integrity in real retail conditions and run smoothly on the line.
For procurement this means predictable cost and availability; for production — shorter start-ups and less waste; for marketing — a clean, consistent pack appearance.
CPP cast polypropylene film vs. BOPP — when cast PP is the better choice
- Sealing performance – Lower seal initiation temperature and high hot-tack enable high-speed packing, especially with heavier or bulky products.
- Mechanical resistance – Cast polypropylene film absorbs impact and point loads better than stiffer BOPP.
- Flexibility – Reduced risk of seal cracking during filling and logistics.
- COF control – Easier adjustment to machine guides and running speeds.
Laminate structures with CPP cast polypropylene film
- Mono-material PP/PP (recyclability driven) – BOPP (outer) // CPP cast polypropylene film (inner) – excellent machinability, strong seals and premium BOPP print surface.
- Barrier without aluminium – Metallised BOPP // CPP – enhanced aroma and moisture barrier for snacks, coffee and spices.
- High-strength laminates – PET // BOPP // CPP or PET // metallised BOPP // CPP – improved drop and puncture resistance for pet food and frozen products.
- Doypack structures – BOPP / BOPPmet // CPP as sealant layer – consistent front panel and reliable sealing, also with zipper or slider.
Printing + CPP film — clean appearance and repeatability
Printing (up to 8-colour flexo) is typically applied on BOPP or PET, while CPP cast polypropylene film works as the inner sealant layer.
During artwork preparation we:
define no-print seal areas
plan easy-open / laser score zones
design windows and matt/gloss contrasts
apply white backing for metallised structures and light colours
The “proof = roll” standard ensures colour and layout consistency across production runs and locations.
Typical applications for CPP cast polypropylene film
Confectionery & snacks – high-speed HFFS, clean edges, strong seals
Coffee & spices – barrier laminate + CPP = stable pack and lower waste
Dry foods (rice, grains, granola) – resistance to sharp edges and dust, smooth VFFS run
Pet food & frozen food – reinforced laminates for strength and tight sealing
Doypack pouches – predictable seal and peel performance, also in mono-PP structures
