Product Introduction

As a professional Automatic Plastic Clamshell Forming Machine manufacturer, LITAI Machine provides high-performance solutions for the efficient production of rigid plastic food packaging, converting plastic sheets into precise, hygienic, and durable containers such as disposable cups, yogurt containers, fruit punnets, and biscuit trays, with machines compatible with PP, PS, PET, and PVC materials and engineered with fully servo-driven systems to ensure stable high-speed operation, accurate forming and cutting, reduced material waste, and consistent production quality.

Automatic Plastic Clamshell Forming Machine Working Principle:

Plastic thermoforming (blister) technology is a plastic processing technology that processes thermoplastic sheets (plates) into various products. First, the plastic sheet (plate) is heated to a softened state in a heating furnace, and then placed in a forming mold, and under the action of external force (vacuum, positive pressure, or mechanical), it is tightly attached to the surface of the mold to form a and detailed contours of the fit surface. After cooling, shaping, trimming, and other processes, the desired product is obtained.
