CPET Shrink Film
CPET shrink film is a heat-shrinkable plastic film made from Crystalline Polyethylene Terephthalate (CPET) with a melting point of 230°C.
Its key advantages include PET-bottle recycling compatibility, high TD shrinkage, and excellent transparency.
It can shrink up to 74% in the transverse direction at 95°C with a wide processing window.
Common applications include tamper-evident neck bands, pharmaceutical sleeves, beverage bottle labels, and any product requiring full PET-stream recyclability.

Shrinkage Curve (Temperature vs. Shrinkage %)

Actual shrinkage depends on film thickness, exposure time, and tunnel conditions — request a batch-specific test report for production planning.
CPET Shrink Film Applications
CPET shrink film is used across pharmaceutical, food and beverage, cosmetics and personal care, and household products industries. Typical applications include tamper-evident neck bands on supplement and medicine bottles, beverage bottle sleeves designed for PET-stream recycling, and any packaging where the label must be recyclable together with the PET container.
Mono-Material Shrink Film: One Polymer, One Recycling Stream
Our CPET shrink film is made of the same polymer family as the PET bottles it decorates — what the packaging industry calls a mono-material solution. Mono-material shrink film means the sleeve and the container share one resin family, so a labeled bottle stays in a single recycling stream instead of needing the label pulled off first. It is the core reason brand owners and sleeve converters specify mono-material film for design-for-recycling programs.
What that means at the sorting line depends on what the sleeve is made of relative to the bottle:
| Container | Sleeve film | Resin-stream match | Design-for-recycling result |
|---|---|---|---|
| PET (RIC 1) bottle | CPET sleeve (RIC 1) | Same PET family | Labeled bottle stays in the PET stream; no sleeve removal needed |
| PET (RIC 1) bottle | PVC (RIC 3) sleeve | Different resin | Recognized PET-stream contaminant; sleeve must be separated |
| PET (RIC 1) bottle | Paper / OPS sleeve | Different material | Requires separate sorting before PET recycling |
Because our CPET grade shares the bottle’s Resin Identification Code 1 and PET’s ~1.32 g/cm³ density band, it does not have to be pulled off before reprocessing. One film — CPET at TD 74 ± 2% shrinkage (ASTM D 1204, 95°C 10s) — covers full-body sleeves on contoured PET bottles while keeping the finished pack mono-material. Supplied as printable rolls, 30–60 μm, 200–2000 mm wide, MOQ 1–3 tons. See our GRS-certified recycled-content RPET film and contoured beverage bottle sleeves.
RIC 1 Recyclable Shrink Sleeve: Same Resin Code as the PET Bottle
Every roll of our CPET film carries Resin Identification Code 1 — the same resin code molded into PET bottles. That is what makes a CPET sleeve a RIC 1 recyclable shrink sleeve: a fully sleeved bottle can be baled, washed, and reprocessed in the standard PET stream with no separate de-sleeving step, supporting bottle-to-bottle circularity.
| Resin code | Resin | On a PET bottle, the sleeve… |
|---|---|---|
| RIC 1 (PET/PETE) | PET / CPET | Matches the bottle; stays in the PET recycling stream |
| RIC 3 (PVC) | Polyvinyl chloride | Recognized PET-stream contaminant; must be separated out |
| RIC 7 (Other) | Mixed / other polymers | Sorted out of the PET stream; generally not bottle-to-bottle |
Two properties let our film survive PET reprocessing intact: a 230°C melting point that withstands standard PET recycling temperatures, and TD 74 ± 2% shrinkage (ASTM D 1204, 95°C 10s) that seats a full-body sleeve on contoured PET bottles. The result is a decorated bottle whose label and container are recovered together as one RIC 1 material, rather than a mixed-resin pack that has to be optically sorted and discarded.
