Focus On Polymer New Molding Equipment
WHAT ARE YOU LOOKING FOR?
Biaxial Stretching Instruments (Lab-Type) & Biaxial Stretching Pilot Lines (Pilot-Type): These are decisive tools for developing next-generation packaging films. By precisely controlling machine direction (MD) and transverse direction (TD) stretch ratios, stretching temperature, speed, and heat-setting processes, they enable systematic study of how stretching parameters affect film crystallinity, orientation, mechanical properties (strength, toughness), barrier performance (oxygen, water vapor), optical properties (haze, gloss), and heat-sealability. This platform is essential for overcoming technical barriers in high-barrier, ultra-thin, and high-strength packaging materials.
Small Precision Multi-Layer Coextrusion Casting Lines: As the foundational step for biaxial stretching, these systems produce pre-made sheets with uniform thickness and stable interlayer structures, ensuring successful subsequent stretching. With minimal material consumption, they enable trials of 3-5 or even 7-layer composite structures (e.g., PP/adhesive/EVOH), making them ideal for developing ultra-high barrier packaging and fresh-keeping films.
Capillary Rheometers and Torque Rheometers: These instruments analyze the rheological properties and processing stability of bio-based/degradable materials like PLA and PBAT, optimizing critical metrics such as heat resistance and toughness. They provide the theoretical foundation and processing windows needed for successful biaxial stretching of these materials.
Process Optimization & Sample Preparation:
Desktop Precision Calenders: Used for developing sheets and packaging materials, these systems help explore how process parameters impact product surface gloss and thickness uniformity.
