How to achieve waterproof and oil-proof performance of printed labels, and which treatment method is the best?

In many application scenarios, printed labels need to have good waterproof and oil-proof performance to ensure that the label information is clearly readable and durable. This performance can be achieved through a variety of treatment methods.
A common method is to use special coatings. For example, a layer of waterproof and oil-proof coating, such as polyvinyl alcohol coating or acrylate coating, is applied to the surface of the label. These coatings can form a protective film to prevent the penetration of water and grease. However, the quality and thickness of the coating will affect its effect. If the coating is uneven or too thin, it may not provide sufficient protection.
Lamination treatment is also an effective way. By covering the surface of the label with a layer of plastic film, such as PET film or BOPP film, the waterproof and oil-proof performance can be significantly enhanced. The advantage of lamination is that it can provide stronger protection and better durability. However, the lamination process may increase costs, and for some labels that require special textures, it may affect the feel and appearance.
Choosing the right printing ink is also crucial. Some specially designed waterproof and oil-proof inks can improve the protective performance of the label to a certain extent. This type of ink usually has good adhesion and chemical resistance, and can resist the erosion of water and grease.
In addition, the choice of label material also has a great impact on the waterproof and oil-proof performance. For example, plastic labels usually have better waterproof and oil-proof performance than paper labels.
Among the many treatment methods, it is difficult to simply determine which method is the best, which depends on the specific application requirements and cost considerations. If the protection performance requirements are extremely high and the budget is sufficient, lamination treatment may be a better choice. However, if you need to balance cost and performance, using special coatings combined with waterproof and oil-proof inks and choosing the right materials can also achieve a relatively ideal effect.
For example, in the field of food packaging, due to frequent contact with grease and moisture, printed labels with lamination treatment are usually used to ensure that the labels are still clearly readable in harsh environments and meet food safety standards. On some daily necessities packaging that are more cost-sensitive, special coatings and waterproof and oil-proof inks may be chosen to achieve a certain degree of waterproof and oil-proof performance.
In summary, achieving the waterproof and oil-proof performance of printed labels requires comprehensive consideration of multiple treatment methods, and choosing the most appropriate method according to the actual situation to achieve the best effect and cost-effectiveness.
