Waterproof cartons are specially designed to protect their contents from moisture and water damage during transportation and storage. Below are detailed descriptions of the materials and uses of waterproof cartons:
Materials for Waterproof Cartons
Wax-coated Paperboard:
The paperboard surface is coated with a layer of wax, forming a waterproof barrier.
Commonly used in scenarios requiring short-term waterproof protection.
Laminated Paperboard:
A plastic film (such as PE film) is applied to the surface of the paperboard to enhance waterproof performance.
The film can be transparent or opaque, depending on the requirements.
Coated Paperboard:
The paperboard surface is coated with a waterproof material such as polyethylene, polypropylene, or other waterproof chemicals.
The thickness and type of coating can be adjusted based on waterproofing needs.
Waterproof Corrugated Paperboard:
Made with specially treated corrugated core and surface papers to increase waterproof performance.
Suitable for heavy-duty or specialized items that require both strength and waterproof protection.
Biodegradable Waterproof Paperboard:
Combines biodegradable materials to achieve both waterproof and eco-friendly functions.
Often used in green packaging and sustainable development projects.
