What is Liner Paper?

Liner paper is a crucial component in corrugated box manufacturing, directly impacting box strength and cost.

Introduction to Liner Paper

Liner paper, also known as linerboard, is the outer and inner layers of a corrugated box. It provides the necessary strength, durability, and printability to the box. The quality and specifications of liner paper can significantly affect the overall performance of the corrugated box.

Types of Liner Paper

There are several types of liner paper, including kraft liner, test liner, and white top liner. Each type has its unique characteristics, advantages, and applications. Kraft liner, for example, is a popular choice for its high strength, durability, and cost-effectiveness.

Importance of Liner Paper Specifications

The specifications of liner paper, such as grammage, thickness, and burst strength, play a critical role in determining the box's overall performance. A higher grammage, for instance, can provide greater strength and durability but may also increase the cost.

Calculating the Cost of Liner Paper

The cost of liner paper can be calculated using the following formula: Cost = (Grammage x Price per tonne) / 1000 For example, if the grammage is 150 gsm and the price per tonne is ₹50,000, the cost would be: Cost = (150 x 50,000) / 1000 = ₹7,500 per 1000 sheets

Unique Data Example

Consider a scenario where a manufacturer is producing 10,000 boxes per day, with each box requiring 0.5 kg of liner paper. The cost of liner paper can be significant, and optimizing the grammage and price can lead to substantial savings.

Case Study: Optimizing Liner Paper Specifications

A leading corrugated box manufacturer in India was facing high costs due to excessive liner paper usage. By optimizing the grammage and price, they were able to reduce their costs by 12% and improve their profitability.

Conclusion

In conclusion, liner paper is a critical component in corrugated box manufacturing, and its specifications can significantly impact the box's performance and cost. By understanding the different types of liner paper, calculating the cost, and optimizing the specifications, manufacturers can improve their profitability and competitiveness.
