Disposable water absorbing and freshness keeping pad for food

Abstract

The invention discloses a disposable water absorbing and freshness keeping pad for food. The pad comprises a film layer and a dry paper layer which are thermally composited through a bonding agent, the film layer is provided with a plurality of through holes which are regularly arranged, the through holes are inverted-conical stereoscopic holes, the large hole surface of the film layer serves as a food contact surface, and the small hole surface of the film layer is bonded with dry paper. According to the disposable water absorbing and freshness keeping pad for the food, the pad is prepared by thermally compositing film with the dry paper, the film is provided with the inverted-conical stereoscopic holes which are in a funnel shape, therefore, direct contact of fiber absorption bodies and the food is isolated, and contamination is avoided; the contact area of the food and the water absorbing pad is decreased, therefore, relative dryness is kept, and bacterium breeding is avoided; the stereoscopic net-shaped structure promotes air circulation and is beneficial for freshness keeping; through the small funnel-shaped holes, juice backflow is avoided, and the water absorbing effect is guaranteed; the phenomenon that the absorption bodies immoderately absorb food moisture is avoided, and therefore the food is kept moisturized and tender.

Description

technical field [0001] The invention relates to the technical field of water-absorbing materials, in particular to a disposable food-absorbing fresh-keeping pad. Background technique [0002] With the progress of society, people have higher and higher requirements for food preservation. Merchants often face the situation that blood and juice in the container are too much to soak the food when preserving especially fresh food such as fish, meat, vegetables, and fruits, resulting in food deterioration.
