General process: plastic sheet - cut - sheet fixed - Heating - Forming - stripping - to feed side - Finished
[Plastic molding material requirements]:
1 plastic molding can only produce more uniform wall thickness of the product, (usually chamfer at slightly thinner), can not obtain significant differences between the wall thickness of plastic products Wall thickness of
2 plastic molding is generally in the range of 1 to 2mm or more thin (small package with the most commonly used plastic thermoforming packaging sheet thickness of 0.15 to 0.25mm)
3 stretch plastic molding products, subject to certain restrictions,injection molded plastic container diameter greater depth than is generally not more than one, in extreme cases will not exceed 1.5
4 plastic molding dimension accuracy, the relative error is generally one percent or more.
The main advantages of plastic thermoforming packaging that saves raw materials, light weight, easy to transport, good sealing performance, comply with environmental green packaging requirements; able to package any special products, packing without additional cushioning material; are visible transparent packaging products, appearance, easy to sell, and are suitable for mechanization and automation of packaging, ease of modern management, saving manpower, improve efficiency
