L’excellence technique au service du client


Here is a list of tests we can conduct in our laboratory:

  • Measurement of impact resistance using falling darts
  • Measurement of light diffusion
  • Measurement of film profile thickness
  • Measurement of the friction coefficient
  • Measurement of surface tension using the ink test
  • Determination of opacity
  • Measurement of films’ tensile properties
  • Measurement of tearing resistance
  • Determination of sealing strength
  • Determination of calorimetric and thermogravimetric profiles
  • Infra-red identification
  • Coupled microscopy

In addition, our laboratory provides clients with certificates of analysis guaranteeing that films produced for them do indeed match client-provided criteria.

Technical Excellence Serving Clients

Our extrusion equipment allows us to produce a wide range of polyethylene films. Whatever your challenge, our team will help you find the film you need.

Our Products Are Found on Several Markets

Our 9,300-square meter (100,000-square foot) plant houses numerous production lines accommodating extrusion and coextrusion of a wide variety of polyethylene resins.

Our films are the product of advanced machining with resins such as HDPE, LLDPE, LDPE, mLLDPE, MDPE and metallocenes.

Thus the films we develop based on a rigorous process control system are found in food and non-food packaging, in agricultural films or any other industrial application using films.



Our specialty films for food packaging made from FDA-grade resins are used for packing coffee, fresh or frozen produce, ready-to-eat foods, meats and snacks, just to name a few.
