Cardboard Tubes : Kraft or Test liner
Why do some cardboard tube manufacturers use testliner, while others use kraft? The choice between using testliner or kraft paper for cardboard tube manufacturing depends on several factors, including cost, strength requirements, environmental considerations, and the intended application of the tubes. Let's explore the reasons why some manufacturers opt for testliner, whilst others prefer kraft paper:
1. Cost Considerations: Testliner is typically more economical to produce compared to kraft paper. As testliner is made from recycled paper and waste fibres, it reduces the reliance on virgin pulp, which can be costlier. For manufacturers looking to reduce production expenses and offer budget-friendly packaging solutions, testliner becomes an attractive choice.
2. Environmental Factors: In recent years, there has been a growing focus on sustainability and eco-friendliness across industries, including packaging. Testliner, being made from recycled materials, aligns with these environmental goals. Manufacturers who prioritise using recycled content in their packaging products may prefer testliner to kraft paper due to its lower environmental impact. On the other hand, some manufacturers may still choose kraft paper as it is produced from virgin pulp obtained through the kraft process. While it might not be recycled, kraft paper is considered more environmentally friendly than bleached papers due to the absence of chlorine bleaching during its production.
3. Strength Requirements: The strength and performance needed for cardboard tubes depend on the products they will contain and the intended use. Kraft paper, with its higher virgin fibre content and strong manufacturing process, offers superior strength and durability compared to testliner. If the tubes need to withstand heavier loads, endure rough handling, or protect fragile contents during transportation, manufacturers may opt for kraft paper as the outer liner. On the other hand, testliner may be sufficient for applications where the tubes do not require extreme strength. For lighter products or situations where the tubes will be used as secondary or tertiary packaging, testliner can provide a cost-effective and functional solution.
4. Aesthetic and Printing Considerations: As mentioned earlier, kraft paper has a natural brown colour that gives it a rustic and organic appearance. This visual appeal may be desirable for certain brands and products seeking to convey a natural, eco-friendly image. Coated kraft paper also offers an excellent surface for high-quality printing, making it an ideal choice for custom branding and marketing purposes. Testliner, while often available in white or brown variants, may not have the same rustic look as kraft paper. However, it can still be suitable for printing and branding on the outer layer of the cardboard tubes, especially if a smoother surface is preferred.
In conclusion, the choice between using testliner and kraft paper for cardboard tube manufacturing depends on a combination of cost considerations, strength requirements, environmental goals, and aesthetic preferences. By understanding the unique characteristics and benefits of each material, manufacturers can make informed decisions to meet their specific packaging needs and cater to the demands of their target markets.
