As a core offering in our comprehensive packaging solutions, we provide high-quality heat shrink capsules in a variety of materials (PETG, PLA, OPS, PVC)—all featuring excellent shrinkage performance to fit various bottle types, with distinct advantages in environmental friendliness and practicality:
PETG: Transverse shrinkage rate up to 75% for precise, wrinkle-free application; recyclable (some grades biodegradable), no toxic gas emission during combustion.
PLA: Excellent shrinkage to fit diverse bottle shapes; made from renewable raw materials (e.g., corn starch), fully biodegradable in nature with zero residual pollution.
OPS: Fast shrinkage response for high production line efficiency; fully recyclable, low production energy, aligned with sustainable trends.
PVC: Excellent low-temperature shrinkage for tight fit; low processing cost, compatible with multiple shrink temperatures, balancing practicality and economy.
