Sheet / Thermoforming

Sheet / Thermoforming

Vacuum Forming Process Overview

  • Vacuum Forming Process

Vacuum forming is a widely used thermoforming process for manufacturing plastic products from heated plastic sheets. During this process, the plastic sheet is heated until it becomes soft and then formed over a mold using vacuum pressure. It is commonly used to produce food packaging trays, disposable containers, blister packaging, and display packaging.

 

  • Role of Masterbatch in Vacuum Forming

Masterbatch is used in the vacuum forming process to provide stable color performance, improve product appearance, and maintain consistent sheet quality during forming. High-quality masterbatch also helps ensure uniform color dispersion and supports stable processing during large-scale thermoforming production.

Vacuum Forming Plastic Sheets

Requirements from Plastic Extrusion Manufacturers

Vacuum forming manufacturers require masterbatch solutions that ensure stable sheet quality, consistent color performance, and efficient production.

01
Excellent Dispersion

Uniform Color in Plastic Sheets

Masterbatch must disperse evenly in plastic sheets to avoid color streaks or uneven appearance after thermoforming.
02
Forming Stability

Reliable Thermoforming Performance

High-quality masterbatch should not affect sheet heating or forming behavior, ensuring stable molding and consistent product shapes.
03
Surface Appearance

Clean and Attractive Product Finish

Packaging products require smooth surfaces and uniform color to maintain a professional and attractive appearance.
04
Cost Control

Efficient Material Cost Management

Manufacturers often look for masterbatch solutions that help reduce material costs while maintaining acceptable product quality.

Masterbatch Solutions for Vacuum Forming Applications

Different types of masterbatch help improve color consistency, sheet quality, and processing stability in vacuum forming production.
