Fully automatic paper bowl machines are designed to manufacture paper bowls from various types of paperboard or cardboard materials. The suitability of paper for these machines depends on several factors including thickness, stiffness, and coating. Here are the types of paper commonly used:
Single Side PE Coated Paperboard:
This type of paperboard has a polyethylene (PE) coating applied to one side, providing moisture resistance.
Suitable for applications where the inside of the paper bowl needs to resist liquid absorption.
Double Side PE Coated Paperboard:
Both sides of this paperboard are coated with polyethylene, offering enhanced moisture resistance compared to single-side coated paperboard.
Ideal for applications requiring higher durability and moisture barrier properties.
Single Side PE Laminated Paperboard:
Similar to PE coated paperboard, but instead of a coating, it has a layer of polyethylene laminated to one side.
Provides a smooth surface and moisture resistance suitable for food packaging applications.
Double Side PE Laminated Paperboard:
Both sides of the paperboard are laminated with polyethylene, offering superior moisture resistance and barrier properties.
Commonly used for premium food packaging requiring high barrier performance.
Aluminum Foil Laminated Paperboard:
Paperboard laminated with a layer of aluminum foil, providing excellent barrier properties against moisture, light, and oxygen.
Used for packaging applications requiring extended shelf life and protection against external elements.
SBS (Solid Bleached Sulfate) Board:
A high-quality paperboard made from bleached chemical pulp, offering a smooth surface and good printing properties.
Suitable for applications where a premium appearance and print quality are important.
Cupstock Board:
Specifically designed for forming cups and bowls, cupstock board is engineered with properties such as stiffness, folding endurance, and liquid resistance.
Tailored for automatic forming and sealing processes in paper cup and bowl manufacturing.
