The stretching of polymer films improves their characteristics in many ways. COLLIN offers laboratory and pilot lines for stretching films for a wide range of thermoplastic materials and compounds. These lines are used for quality control and for the development of new products and processes. They can also be used for the production of narrow films.

High variability is also shown by the option of one or two stretching gaps. Due to the compact design, the film can easily be threaded.

Design of a COLLIN stretching line:

  • Extrusion group
  • Stretching unit
  • Take-off
  • Winder

Advantages

  • Improved film characteristics
  • Extension of the application possibilities of the film
  • Optimisation of mechanical characteristics such as tensile strength, stretching as well as barrier effect against different media
  • Compact design
  • Film can manually be threaded
  • Comfortable cleaning

Variability

  • Selection between 1 or 2 stretching gaps
  • Use of 7 drives for 1 stretching gap and 10 drives for 2 stretching gaps for optimal graduation of friction and speed
  • Variation of the length of the stretching gap
  • Variation of the gap of the contact rolls
  • Selection of the temperature of all roll groups

High variability is also shown by the option of one or two stretching gaps:

MDO Single Stretching Unit
A variety of polymers, especially PP, PE but also PA is monoaxially stretched in order to considerably improve the mechanical, optical and barrier characteristics. The stretching essentially occurs in the short gap procedure in one stretching gap with adjustable length of the stretching gap.

MDO Dual Stretching Unit
This system of a two-gap stretching line was developed in industry for the production of breathable films. The special feature of these films is a high percentage of mineral fillers. This task requires a special design of the machine and modified processing parameters.

Applications

  • Short-gap stretching for films, e.g., made of PP and PE
  • Long-gap stretching with IR additional heating for films, e.g., made of PET

Materials

  • Thermoplastic materials and compounds such as PP, PE, PET, PA
  • Processing of high-tech polymers with temperatures of up to 400°C

Use

  • Product development
  • Quality control
  • Pilot production
  • Production of narrow films

Customers

  • All manufacturers of polyolefins (PP, PE) and PA
  • Processing companies in the stretch film sector
  • Manufacturers of mineral fillers, compounds and films for breathable applications
