Embodiment 1 and 2、 comparative example 1 to 5

[0045] In all the examples and comparative examples, the droplet absorbent sheet was produced through the above-mentioned lamination step, cutting step, and product stacking step. In all the examples and comparative examples, the porous resin film is mainly composed of a basis weight of 25g / m 2 Made of polyethylene, and the liquid-absorbing layer is mainly composed of a basis weight of 52g / m 2 It is composed of airlaid pulp. Glycerin fatty acid esters are used as surfactants mixed into the porous resin film. These layers are laminated by thermal lamination to form a laminated body; then, the laminated body is cut into a 65 mm×120 mm sheet with a cutter, thereby obtaining a droplet-absorbing sheet. After that, these droplet-absorbing sheets were stacked in a packing box into a stack of 100 sheets. As shown in Table 1, the examples and comparative examples contain different amounts of surfactants. In addition, as shown in Table 1, for Examples 1 and 2 and Comparative Examples 4...

Abstract

In a method of manufacturing a drip absorbent sheet, the drip absorbent sheet having: a plurality of holes through which drip, which is juice released from foodstuff, can pass; a porous resin film containing 1 to 3% by mass of a surface-active agent, and a liquid absorbent layer laminated with the porous resin film. The method includes at least: a laminating step of laminating the porous resin film and the liquid absorbent layer; a cutting step of cutting a laminate obtained in the laminating step into a product of a predetermined product dimension; and a product stacking step of stacking the product in sheets after the cutting step into stacks of a plurality of sheets. In at least one of the cutting step and the product stacking step, a contactless charge neutralization process is performed with respect to a front surface side of the porous resin film.

Description

Technical field [0001] The present invention relates to a method of manufacturing a droplet-absorbing sheet. Background technique [0002] In food departments such as supermarkets, food such as fish and meat is sold in a state of being divided into predetermined parts, wrapped in a transparent film, and placed in a tray. In this type of sales, food stays on the display shelf for a long time, and droplets tend to accumulate in the tray. Since the liquid droplets accumulated in the tray not only impair the appearance but also accelerate the deterioration of the food, a droplet absorbent sheet for absorbing the liquid droplets is usually laid on the tray on which the food such as meat and fish releases the liquid droplets is placed. [0003] The inventors have known a droplet absorbent sheet in which a porous resin film is arranged on the surface of a liquid absorbent layer. An opaque porous plastic sheet with a large number of three-dimensional holes is arranged on the surface of a...
