1. Moisture resistance requirements usually come from the actual transportation environment
Customers commonly enquire if moulded pulp packing can be handled with moisture-proof methods in various project communications. This is generally due to the stress of the actual transportation environment. Pulp materials are especially likely to absorb moisture in regions with high humidity or near water. When the moisture level goes up, it might change the shape and perhaps make it weaker. So, while making packaging solutions, you shouldn't just assume that moisture-proof treatment is needed from the start. Instead, you should think about the transportation cycle and the climate in which the package will be used.
2. It is possible to keep moisture out, but to different degrees.
Yes, moulded pulp packaging can be treated to be moisture-proof from a technical point of view, but the important thing is what level it can reach. Some common approaches are surface coating treatment, adding additives to raw materials, or changing the structure of the material to make it less likely to come into contact with moisture. The benefits of different schemes are very variable. Some just slow down moisture absorption, while others might make moisture resistance much better. So, when you have to make a choice, you need to have a clear aim instead of just trying to find something that is "completely waterproof."
3. Treatment to make things waterproof will effect expenses and the environment.
In real life, whether moulded pulp packing can be treated to be moisture-proof also depends on how much it costs and how it affects the environment. Some moisture-proof solutions may add steps to the process, which would raise the final cost. On the other hand, using the wrong materials could make the product less biodegradable. So, a lot of projects will go with a middle ground approach, like employing water-based coatings, to make sure they are somewhat resistant to moisture while having as little effect on the environment as possible.
4. Not every project needs to be moisture-resistant.
A lot of people think that all pulp packaging needs to be treated to keep moisture out. In fact, whether moulded pulp packing can be treated to be moisture-proof depends more on how it will be used. No further treatment is needed if the product will be moved a short distance or if it will be stored or shipped in a dry place. If the product will be stored or shipped for a long time, it is even more important to make it more resistant to moisture. So, the choice of solutions should be based on what people really need, not on rules that everyone has to follow.
5. In short, it is possible to keep moisture out, but it takes a balance.
In general, moulded pulp packaging can be treated to be waterproof. The important thing is whether it is essential and which procedure to use. A reasonable design can help find a balance between performance, cost, and protecting the environment, which leads to a better solution for real-world use.
