OPS (oriented polystyrene) heat shrinkable film is a new type of packaging material that meets the requirements of environmental protection. OPS heat shrinkable film has high strength, high rigidity, stable shape, and has good gloss and transparency. Convenient processing, easy coloring, good printing performance, and extremely high printing resolution. For the trademark that continues to pursue exquisite printing, it is completely a material progress. Due to the high shrinkage rate and strength of OPS film, it can be closely fitted with containers of various shapes, so it can not only print exquisite patterns, but also meet the use of various novel packaging containers with different shapes. This non-toxic, tasteless, oil-resistant, and food hygiene standard film can enable designers to adopt eye-catching colors, realize 360 label design, and give full play to creativity and imagination, so that beverages and other goods in the use of the label pattern more vivid, highlighting the image on the shelf, resulting in an unexpected container effect.

Transparency

After heating and plasticizing, the rigidity of the polymer chain segment is improved, and the intermolecular force is increased, so it shows the characteristics of hard and transparent at room temperature. In the optical performance of OPS, a very important one is that it can pass through all wavelengths of visible light, which makes the OPS film have a high degree of gloss. These two points are the basic requirements for material in label production. Without certain rigidity, the trademark will not have a certain stiffness, and it will not be able to meet the requirements of the continuously speeding up labeling machine. Similarly, the high transparency of the film, easy to color the characteristics of the production of exquisite trademarks laid the foundation, you can design a variety of different shapes and patterns of the label.

high shrinkage

OPS makes up for the defects of the shrinkage film of the traditional blowing process, and its transverse shrinkage rate can be as high as 80%. The index requirement of this high shrinkage rate can make the trademark fit on containers of different shapes, highlight the body of the container, make the packaging more vivid, and also achieve the effects of anti-riot cracking and sealing hygiene.
