What's the Difference Between Wax Coating Machine and Non-Plastic Coating Machine?

If you work in packaging or manufacturing, you may have come across both wax coating machines and non-plastic coating machines. These two pieces of equipment are often confused, but they serve distinct purposes. This article breaks down their key differences to help you understand which one fits your needs.
 

Core Definition

A wax coating machine is designed to apply a layer of wax onto materials like paper, cardboard, or certain films. Its main goal is to add specific functional benefits, such as water resistance or surface protection, to the treated material.

In contrast, a non-plastic coating machine applies coating materials that contain no plastic components. These coatings are typically water-based, plant-based, or mineral-based. The machine's primary focus is to create a protective or decorative layer while avoiding plastic, aligning with eco-friendly packaging trends.
 

Coating Materials

Wax coating machines use wax as their core coating material. Common types include paraffin wax, microcrystalline wax, and food-grade beeswax. These waxes are solid at room temperature and require heating to melt before application.

Non-plastic coating machines rely on non-plastic substances. Examples include water-based acrylics, plant-derived resins, and mineral-based coatings. These materials are often liquid or semi-liquid at room temperature and don't need high heat to prepare for coating.
 

Typical Application Scenarios

Wax coating machines are most used in scenarios where water resistance or moisture protection is critical. For instance, they treat paper bags for snacks, cardboard boxes for frozen foods, or paper wraps for takeout. The wax layer prevents liquids or moisture from seeping through the material.

Non-plastic coating machines are preferred for projects that prioritize plastic-free packaging. This includes coating paper cups for beverages, biodegradable film for produce packaging, or cardboard for cosmetic boxes. The non-plastic coating ensures the final product meets environmental standards and consumer demand for sustainability.
 

Working Principles

A wax coating machine works by first heating solid wax until it becomes a liquid. The liquid wax is then evenly spread onto the target material using rollers or sprayers. After application, the wax cools and solidifies quickly, forming a thin, protective layer.

Non-plastic coating machines use a different process. The non-plastic coating material (usually liquid) is applied via rollers, blades, or spray systems. Depending on the coating type, it may dry at room temperature or require low heat to cure. This curing step helps the coating bond firmly to the material without relying on plastic components.
 

Conclusion

Understanding the differences between a wax coating machine and a non-plastic coating machine comes down to their materials, uses, and operations. A wax coating machine excels at adding water resistance with wax-based layers, while a non-plastic coating machine focuses on plastic-free, eco-friendly protection. Knowing these distinctions helps you choose the right equipment for your packaging or manufacturing needs.
