Лайнер Oyster — отраслевой стандарт для производства белой гофроупаковки. Made from Kraft paper, this material features high recycled content making it up to 100% . The liner is a slightly off-white color, and because it is not fully bleached like typical white printing paper, the white maintains kraft brown undertones throughout. In most cases, it is the best choice for white corrugated packaging as it is cost-effective, readily available and offers more accurate color output when printed on. However, because of the more natural undertones, printing on this material will offer a 'no gloss' finish, making designs look more flat.

Corrugated Strength Tests

Edge Crush Test (ECT)

Force is applied perpendicular to the edge of the corrugated board until it buckles. The results provide accurate representation of the material's strength, durability and stack resistance for heavier loads. The resulting value is shown in pounds per linear inch of load-bearing edge and is reported in ECT ratings.

Note: 32 ECT is the most commonly used for corrugated material.

Bursting Test

The burst test, otherwise known as the Mullen Test, challenges the durability of the corrugated fiberboard’s surface. The burst test determines the amount of force required to puncture the liner board. The resulting value is given in pounds per square inch.

Note: 200# means 200 pounds per square inch of force applied to the face of the liner board.
