CS-H is a versatile film used for a wide range of applications in the food field, including frozen and refrigerated products, as well as in the industrial and electronics fields.

  • Gas barrier properties
  • Non-curl
  • Label adhesion
  • Transparency and gloss
  • High strength
  • Automatic machine compatibility
  • Suitable for heat sealing
  • Pinhole resistant (frozen)
  • Flavor retention property


PBT resin has excellent transparency, gloss, and aroma retention properties. Using it as the outermost layer protects the NY layer, which gives strength to the film, and provides pinhole resistance. The film does not curl, making it suitable for automatic bag feeders. This is a versatile film can be used in a wide range of fields, from food in general to industrial and electronics. A wide range of products are available for various contents and applications.

  • Pinhole resistance

  • Suitable for automatic feeding machine

  • High aroma retention property

  • High label adhesion


  1. Pinhole resistance under frozen conditions

    Pinhole resistance suitable for frozen distribution

    The flexibility characteristic of co-extruded multilayer films suppresses pinhole occurrence, and polybutylene terephthalate (PBT) resin in the outermost layer protects the strong nylon resin and improves cold pinhole resistance.

  2. For automatic food filling machine

    Since the opening does not curl, it is suitable to high-speed packaging machine and improves productivity.

    Polybutylene terephthalate (PBT) resin is less prone to water absorption than nylon resin, reducing the curling of the aperture. This makes it ideal for automatic bag feeders that require performance in opening apertures.

  3. Highly flavor retention

    Maintains the aroma and flavor of freshly prepared food.

    Aromatic polyester resins such as polybutylene terephthalate resin (PBT resin) have the property of retaining the aroma and flavor of the contents. This property has been used to impart a high aroma- retention property to the film.

  4. Easy labeling pouch

    Good label adhesion

    Polybutylene terephthalate resin (PBT resin) has a very low water absorption rate and is used as the outermost layer. This minimizes moisture absorbed by the film surface and prevents adhesive loss with the label glue. PBT resin is a hydrophilic resin, and since most label glues are acrylic resin, which is also a type of hydrophilic resin, this technology takes advantage of the characteristics that resins with the same properties tend to bond together.
