Blown films

In blown films, input plastic material is melted and inflated into bubble form, then rolled into finished film rolls or used for the next processing steps. The level of films thickness and clarity depends on the end-products’ requirements.

Filler masterbatch

PE filler, Transparent filler, and Bio filler are common types used in blown films, such as shopping bags, roll bags,…  

Features:

  • Save production cost
  • Shorten production cycle thanks to CaCO3’s great thermal transmission ability
  • Improve several properties of end-products: stiffness, impact resistance,…
  • Increase the stability in manufacturing process
  • Enhance the printability
  • Biodegradability (for bio filler)

Color masterbatch

Vinplastics provides a wide variety of types of color masterbatches that fit end-products’ requirements

Features:

  • Exact color as required
  • High level of compatibility with most of standard resins
  • Great dispersion on plastic surface
  • Good color fastness
  • Functionalities added (anti UV, anti aging,…)
  • Easy to store and delivery

Additives

Vinplastics provides a wide range of additives to improve a specific function of end-products

Features:

  • Antiblock additive and slipping agents: prevent the adhesion between two adjacent film layers, thus improving the quality and efficiency of end-products
  • Processing aid: reduces the friction between plastic and equipment surface, thus stabilizing the flow of polymer, improving productivity and quality of end-products
  • Antifog additive: used in food packaging to prevent the moisture condensation on the film surface, thus improving the films transparency
  • Antistatic additive: prevents the static charge build-up on plastic surface, resulting in safer and more effective manufacturing process as well as cleaner packaging film
  • Desiccant: absorbs moisture in materials, thus minimizing the presence of defects during processing, such as: bubble, fisheye,…

Filler masterbatch

PE filler, Transparent filler, Bio filler are common types of filler masterbatches used in agricultural films 

Features:

  • Save production cost
  • Shorten production cycle thanks to CaCO3’s great thermal transmission ability
  • Improve several properties of end-products: flexural strength, impact strength,
  • Increase the stability in manufacturing process
  • Enhance the printability
  • Biodegradability (for bio filler)

Color masterbatch

Vinplastics provides a wide variety of types of color masterbatches that fits end-products’ requirements.

Features:

  • White masterbatch: increases the whiteness and brightness for films, promotes plants photosynthesis. Besides, Vinplastics white masterbatch also prevents the impact of UV lights on plants.
  • Black masterbatch: widely used in mulch films as it not only creates color for films, but also minimizes negative impacts of UV light and cools the soil, thus improving the crop productivity 

Additives

Vinplastics provides a wide range of additives to improve a specific function of end-products.

Features:

  • Anti-UV additive: commonly used in greenhouse films to prevent degradative impacts of UV light on films, thus improving films’ longevity as well as protecting plants 
  • Antiblock additive and slipping agents: prevent the adhesion between two adjacent film layers, thus improving the quality and efficiency of end-products
  • Processing aid: reduces the friction between plastic and equipment surface, thus stabilizing the flow of polymer, improving productivity and quality of end-products
  • Antifog additive: used in food packaging to prevent the moisture condensation on the film surface, thus improving the films transparency
