A pit box (also known as a corrugated box) is a packaging container made of corrugated paper (pit paper) bonded to cardboard. It is often used for mid-range product packaging, between the inner packaging and the outer box. Its core characteristics include cushioning, pressure resistance and visual presentation.

Main features and uses Materials and structures

Face paper Materials: commonly used powder paper (single-sided white/gray), double powder paper (double-sided white) or coated paper, the gram weight range is usually 250g-450g. Corrugated type: According to the corrugated type, it is divided into A, B, C, E, F, etc., such as E pit (thin type) and C pit (commonly used in North America). Different corrugated types correspond to different compression ratio coefficients (such as 1.59 for A corrugated, 1.27 for E corrugated). Structural form: single corrugated (single wall), double corrugated (double wall), etc., through the mounting process to enhance the load-bearing capacity. Application field

Applicable scenarios: Product packaging that requires a certain load-bearing, such as digital products, toys, cosmetics, food, etc. Advantages: Improve the display effect of goods through color matching and printing process, suitable for consumption scenarios that need to visually display the appearance of packaging. Production process Design and plate making: Design documents according to requirements and output film (film plate making). Printing and mounting: After printing the surface paper, it is bonded with corrugated paper to form a composite structure. Die cutting and forming: The shape is cut using a knife mold and the final assembly is completed by the sticky box process.
