Shrink label for plastic bottles may seem easy, but even the slightest carelessness can lead to wrinkling, misalignment, or peeling. 35% of consumers judge a product based on how well the label adheres. Zhejiang Zhongyu Technology Co., Ltd. has revealed its specialized shrink label production process for plastic bottles to ensure optimal adhesion.
Three Key Elements of Shrink Labels: Material, Heat, and Adhesion
PETG, PVC, and OPS materials require different shrinkage rates, and the materials must be well compatible with the bottle.
Ideal temperature: 120°C–160°C, depending on the resin thickness.
Eliminate static electricity on plastic bottles to prevent dust.
| Variable | Standard Labels | Zhongyu Precision Series | Benefit |
| Shrink Tolerance | ±8% | ±0.5% (AI-controlled) | Wrinkle-free finish |
| Ink Adhesion | 3B (tape test) | 5B (chemical bonding) | Resists IPA wiping |
| Thickness Range | 40-50μm | 35-55μm (gradient zones) | Conforms to curves |
| Recovery Time | 48h (full adhesion) | 8h (fast-cure polymer) | Accelerated filling |
| Eco-Profile | Non-recyclable mix | Mono-material PETG | Streamlined recycling |
Q: Why does the label wrinkle at the bottle seam?
A: The shrink label for plastic bottles' seam irregularity exceeds the shrinkage capacity of standard film. Our product's biaxial stretch absorbs over 15% of the stress, reducing scrap rates.
Q: Can labels be applied to cold bottles in a humid environment?
A: Yes, but the bottles must be preheated to at least 25°C and the relative humidity must be below 45%. Plastic bottle shrink labels use a hydrophilic coating to protect against moisture.
Q: How cold can plastic bottle shrink labels withstand?
A: Flash freezing can cause labels to break. Our innovative product, when used correctly, can withstand temperatures as low as -30°C. In tests conducted at 25°C, the shrink labels for plastic bottles showed no damage.
Shrink lable for lastic bottles with diameter deviations greater than 0.3 mm are rejected.
Three-zone gradient: 130°C (preheat) → 150°C (shrink) → 100°C (set).
A servo-driven mandrel achieves 0.1° labeling accuracy.
1.Pharmaceutical customers achieve 100% FDA visual inspection pass.
2.Craft brewers create vintage-inspired bottle aesthetics.
3.Chemical brands remain legible after 12 months of outdoor exposure.
