Explainer: Kraft vs Testliner
Kraft paper and Testliner paper are two commonly used types of paperboard that are widely used in the packaging industry. While both papers are used for similar purposes, they have distinct differences that set them apart. In this article, we will discuss the differences between Kraft and Testliner paper.
Kraft paper is made from virgin pulp obtained from softwood trees. It is a high-strength paper that is designed for heavy-duty applications. The strength of Kraft paper comes from the long fibres found in softwood trees. These fibres are tightly woven together during the paper-making process, creating a strong and durable product.
Kraft paper is commonly used for packaging heavy items such as cement, fertilizer, and chemicals. It is also used in the construction industry for building materials, such as roofing felt and insulation. Kraft paper is resistant to tears, punctures, and moisture, making it an ideal choice for these applications.
On the other hand, Testliner paper is made from recycled pulp and is less strong than Kraft paper. It is a cost-effective option that is used for less demanding applications. Testliner paper is commonly used for packaging lightweight items such as food products, cosmetics, and consumer goods.
Testliner paper has a lower strength than Kraft paper due to the shorter fibres used in the recycling process. However, it is still a reliable option for many packaging needs. Testliner paper is also used in the printing industry for creating packaging with custom designs. In terms of appearance, Kraft paper has a brown colour due to the virgin pulp used in its production. Testliner paper can come in a variety of colours, including white, brown, and gray.
Both Kraft and Testliner papers have their advantages and disadvantages. Kraft paper is stronger and more durable, but it is more expensive due to the use of virgin pulp. Testliner paper is cheaper, but it is not as strong as Kraft paper.
In conclusion, Kraft paper and Testliner paper are both important materials used in the packaging industry. Kraft paper is a high-strength, durable option that is ideal for heavy-duty applications, while Testliner paper is a cost-effective option that is suitable for less demanding applications. Understanding the differences between these two materials can help you choose the best option for your packaging needs. Just Paper Tubes only use Kraft paper for our brown tubes, this is because we believe its additional strength benefits are worth the higher costs.
