Pure white food grade PP: The uniform white appearance gives the product a clean and professional visual impression, effectively covering the fine ice crystals that may be generated during the freezing process, presenting a neat and uniform high-quality texture, and enhancing consumer trust.

Excellent low-temperature resistance: The selected PP material can maintain excellent toughness and impact resistance even in deep freezing environments, avoiding the risk of cracking caused by low-temperature brittleness and providing safe protection for tofu from the factory to the dining table.

Precision molding support: The vacuum forming process closely adheres to the shape of tofu, providing uniform sidewall support, effectively preventing deformation and breakage of tofu during transportation and stacking, ensuring the integrity of the product form.

Reliable heat sealing performance: The flat sealing edge ensures a firm seal with the cover film, creating an efficient barrier environment and fundamentally preventing tofu from becoming hard, losing its texture, and experiencing "freezing and burning" due to moisture sublimation during the freezing process.
