How do PET shrink sleeves differ from PVC or OPS shrink sleeves?

Shrink sleeves are widely used for full-body labels, tamper-evident seals, and 360° branding. Among them, PET, PVC, and OPS are the three major film types—but they differ in performance, environmental impact, and cost.

1. Shrink Rate & Performance

PET (PETG) Shrink Sleeves

High shrink rate (up to 75–80%)

Excellent clarity and gloss

High durability & impact resistance

Suitable for high-contour bottles (beverage, cosmetics, personal care)

PVC Shrink Sleeves

Medium shrink rate (60–65%)

Easy to shrink, forgiving in production

Good clarity

Suitable for general-purpose shrink applications

Lower cost

OPS Shrink Sleeves

Lower shrink rate (55–60%)

Very stable film, good for thin walls

Matte-like, natural look

Suitable for delicate or light-contour containers

2. Environmental Impact

PET

Most environmentally friendly

100% recyclable within PET recycling stream

Widely accepted for food and beverage packaging

PVC

Least eco-friendly

Releases harmful HCl gas when incinerated

Difficult to recycle

OPS

Better than PVC but still not widely recyclable

Limited recycling infrastructure

3. Strength & Durability

PET: Strongest; high toughness, tear resistance, and chemical resistance

PVC: Soft and flexible, but lower strength

OPS: Brittle; can crack or split in cold conditions

4. Cost

PVC: Lowest cost

OPS: Medium cost

PET (PETG): Highest cost, but also best performance

5. Printing Quality

PET: Excellent ink adhesion; high-quality graphics

PVC: Good printability

OPS: Good printability but less vivid than PET
