Vacuum Forming box, also known as bubble shell or vacuum cover, is a plastic box-shaped packaging made by heating and softening the sheet, adsorbing it on the mold surface through vacuum, and then cooling it. It is usually made of polystyrene (PS), but other materials such as polyethylene terephthalate (PET) may also be used. Vacuum Forming boxes are widely used in the packaging of food and electronic products.

Process Introduction

Principle and Application

Vacuum Forming is a plastic processing technology. Its basic principle is to heat a flat plastic hard sheet to a soft state, then use vacuum technology to adsorb and fix it on the mold surface, and then cool it to form the desired shape. This process is widely used in many fields such as plastic packaging, lighting fixtures, advertising production and interior decoration.

Packaging Types

Vacuum Forming packaging products include Vacuum Forming, tray, Vacuum Forming box and other types. Among them, the characteristic of Vacuum Forming box is that its lid and container are integrally formed, which is commonly seen in Japanese fast food boxes. The bottom is made of black PS material, and the cover is made of transparent PET material.

Equipment and Classification

The production equipment of Vacuum Forming packaging mainly includes Vacuum Forming forming machine, punching machine, sealing machine, high frequency machine and folding machine. Through these equipment, various types of Vacuum Forming packaging products can be produced, such as card-insertion type, Vacuum Forming card type, double Vacuum Forming, half Vacuum Forming, folding Vacuum Forming and trifolding Vacuum Forming.

Main Features

Vacuum Forming box packaging has many significant advantages:

Resource Saving

Vacuum Forming box packaging can effectively save raw materials, and at the same time, due to its light weight and easy transportation, it also reduces logistics costs.

Good Airtightness

Vacuum Forming box packaging has good airtightness, which can effectively prevent products from being contaminated by the outside world and ensure the hygiene and safety of products.

Green and Environmental Protection

Vacuum Forming box packaging conforms to the modern green environmental protection concept, which not only reduces the amount of packaging waste, but also improves the recycling rate of packaging.

Diverse shapes

Vacuum Forming packaging can adapt to products of various shapes without the need for additional cushioning materials, thus simplifying the packaging process.

Increase sales

The design of Vacuum Forming packaging can attract consumers' attention and help increase product sales.

Improve grade

High-quality Vacuum Forming packaging can improve the grade of products, making them more attractive, thereby bringing higher economic benefits to enterprises.

Application scenarios

Vacuum Forming boxes are often used for the packaging of electronic products, digital products and other commodities. For these products, Vacuum Forming boxes can not only protect them, but also promote sales and improve the grade of products.
