Plastic films: measure, innovate, industrialize
On plastic films play a crucial role in many industrial sectors: packaging, agriculture, construction, electronics, medical, etc. Their quality, functionality and durability are based on rigorous control of mechanical, thermal and surface properties, often subject to complex usage constraints (stretching, folding, environmental conditions, chemical interactions).
Rheonis supports manufacturers in the characterization, optimization and control of plastic films, combining multi-physical expertise and a tailor-made approach adapted to each sector.
A complete range of services related to plastic films
Beyond measurement, Rheonis offers an integrated approach covering the entire industrial life cycle of plastic films:
- Multi-physical measurements : rheology, mechanics, tribology, barrier properties, dynamic behaviors.
- Formulation and process studies : extrusion, blowing, calendering, coating, printing.
- Assessment of conditions of use : mechanical constraints, aging, product-material compatibility.
- Optimization and industrialization : adjustment of recipes, choice of processes, reduction of variability.
- Training and skills transfer for your R&D, quality and production teams.

Measuring plastic films: approaches adapted to industrial challenges
Plastic films have complex behaviors that are essential to characterize in order to guarantee their performance and reliability.
Rheonis uses multi-scale and multi-physical approaches adapted to your issues:
- Mechanical measurements : tensile strength, elongation, creep, hardness, perforation.
- Tribology and friction : slipperiness, adhesion, wear, film/film or film/machine friction.
- Physical chemistry : gas and moisture permeability, barrier properties, interactions with products.
- Thermal and phase transitionse : melting behavior, crystallization, dimensional stability.
- Dynamic behaviors : submission to process constraints (speed, stretching, impact).
These measures make it possible toanticipate defects, make processes more reliable and accelerate developments.
