Laboratory Blown Film Lines
The supplier:
Hapro
Laboratory blown film lines are used to evaluate the behaviour of film materials during extrusion with film-bubble blowing.
This configuration makes it possible to produce film samples under conditions close to industrial blown-film technology, but on a laboratory scale.
Main Tasks:
- evaluation of PE and PP film grades;
- assessment of film-bubble stability;
- comparison of additives, pigments, antiblock additives and slip agents;
- preparation of samples for thickness, transparency and surface evaluation;
- initial development of blown-film formulations.
Applications:
Primarily suitable for polyolefins and film materials. It can be useful for manufacturers of packaging films, masterbatches and additives for film processing.
