Quality Approaches

The produced paper products are carefully examined and approved by the laboratory and quality control unit before being dispatched to storage. The tests conducted in this process evaluate various physical and chemical properties of the paper.

Here are the main paper strength tests performed in our laboratory and quality control unit:

Burst Test

This test measures the paper's durability and resistance to tearing. The paper is subjected to pressure applied to its center until it reaches its bursting point.

Tear Test

This test measures how easily the paper can be torn, starting from its edges. It evaluates the paper's tear resistance.

Tensile Test

A test conducted to measure the paper's resistance to tensile strength. The paper is stretched from both ends until it reaches the breaking point.

Smoothness

The surface smoothness of the paper is evaluated in terms of print quality and tactile feel. A smooth surface provides better print quality.

Porosity B and Porosity G Tests

These tests measure the air permeability of the paper and evaluate its porosity. Porosity B and Porosity G tests determine the paper's air permeability level using different measurement methods.

UV Color L Test

This test measures the paper's ability to retain its color against UV rays. It assesses the risk of color fading in outdoor conditions.

Basis Weight

A test that measures the weight of the paper per unit area, also known as grammage.

Moisture

This test measures the amount of moisture contained in the paper, providing information about its dryness and storage conditions.

Short-span Compression Test (SCT)

This test measures the paper's resistance to compressive forces over short distances and is particularly important in the production of corrugated cardboard.

TSO/TSI (Transversal Direction Stiffness Index)

A test that measures the stiffness and elasticity of the paper in the transverse direction.

Caliper (Thickness)

This test measures the thickness of the paper, which provides information about its durability and flexibility.

CCT (Corrugated Crush Test)

This test measures the crush resistance of corrugated paper, which is particularly important for packaging papers.

CMT (Concora Medium Test)

A test that measures the crush resistance of the medium layer of corrugated cardboard.

RCT (Ring Crush Test)

This test measures the ring crush resistance of the paper, evaluating its vertical load-bearing capacity.

Internal-Bond-Test (Z-Pull Test)

This test measures the internal bonding strength of the paper, evaluating the adhesion force between its layers.

Cobb60

A test that measures the water absorption capacity of the paper. The amount absorbed is measured by applying water to the paper surface for a specified period.

These detailed tests conducted in our laboratory and quality control unit guarantee that we provide our customers with the highest quality paper products.
