Description

Basic information for this Heat Shrink Sleeve Machine/ Automatic Shrink Labeler/ Bottom Sleeve Machine:

Heat Shrink Sleeve Machine/ Automatic Shrink Labeler/ Bottom Sleeve Machine Commonly used heat-shrinkable label film materials primarily include three types: PETG, PVC, and OPS
PETG film exhibits high shrinkage rate, making it suitable for packaging irregularly shaped bottles. It demonstrates excellent stiffness and post-printing glossiness. The material exhibits high transport stability, with minimal shrinkage below 60°C. The shelf life is approximately 6 months from the date of production. It is the most expensive option.
PVC film is suitable for conventional bottle shapes with excellent stiffness. The shelf life is approximately 6 months from the date of production. With moderate pricing, it will continue to dominate the domestic heat-shrinkable label market for an extended period.
OPS film boasts the lowest production cost, with unit area costs approximately 75% of PVC. Its low density results in label thickness typically ranging from 30μm to 40μm. The material exhibits natural shrinkage characteristics, necessitating strict transportation requirements and thermal insulation measures. With a limited shelf life of 3 months from the factory date, it demands higher precision from automated labeling equipment and has a narrower market applicability range.
Material selection requires comprehensive consideration of factors such as shrinkage rate, stiffness, cost, storage stability, and processing requirements. Due to environmental regulations and the increasing use of custom-shaped bottle packaging, the consumption of PETG films is expected to grow rapidly. PVC films will continue to dominate the market for a considerable period due to cost considerations. The usage of OPS films is not anticipated to see significant growth.

Working Principle for Heat Shrink Sleeve Machine/ Automatic Shrink Labeler/ Bottom Sleeve Machine:

The design and technical requirements for Heat Shrink Sleeve Machine/ Automatic Shrink Labeler/ Bottom Sleeve Machine and heat-shrinkable labels must comprehensively consider end-use application needs, film material properties, and subsequent processing techniques. Common film materials include OPS, PETG, and PVC, whose selection directly impacts label cost, processing performance, and final product quality. OPS heat-shrinkable labels are the most cost-effective, PVC labels are slightly more expensive, and PETG labels are the most costly. For labels used on irregularly shaped bottles or those requiring high glossiness, PETG films should be prioritized; if cost efficiency and standard bottle shapes are desired, PVC films may be selected.
