A method for producing a thick film type of non-fogging sheets having a thickness of 30 .mu.m or more comprises the steps of: preparing a solvent-free composition comprising (a) a polymer, (b) a hydrophilic monomer and (c) a surface active agent and having a viscosity of 50,000 cP or less, applying this composition as a coating on the surface of a backing film without recourse to any solvent, and crosslinking the thus coated composition by exposure thereof to ionizing radiation, thereby forming a hydrophilic film having a thickness of 30 .mu.m or more.

A battery packet (50) comprises a battery case (51) formed by processing a battery case forming laminated sheet (10), a battery 50a contained in the battery case (51), and tabs (59, 60) extending outside from the battery case (51). The battery case forming laminated sheet (10) is formed by laminating a first base film layer (1a), i.e., an outermost layer, a metal foil layer (2), and a heat-adhesive resin layer (3) in that order. The first base film layer (1a) is a biaxially oriented polyethylene terephthalate resin film or a biaxially oriented nylon resin film. The metal foil layer (2) is an aluminum or copper foil. The heat-adhesive resin layer (3) is formed of a polyolefin resin, more preferably, of an acid-denatured polyolefin resin.

An instrument for chemical and microbiological tests comprises a sample container for temporarily storing a liquid sample; a plurality of sample-holding portions formed on the bottom face of the sample container; and a liquid-absorbent body capable of coming in contact with the liquid sample so that the body can absorb the excess sample, when the liquid sample is introduced into the container, while retaining the sample to be held on the sample-holding portions. This instrument can be used in a chemical or microbiological test wherein a sample is used in a relatively small amount and, in particular, those requiring a large number of reactions and cultivation. Moreover, the instrument does not require the dispensation of a sample to each reaction system and does not cause any scatter of the sample in the surroundings.

A test kit for a chemical test or microbiological test, which comprises at least one independent sample-receiving part on a support is disclosed. The test kit of the present invention is usable for various chemical and microbiological tests which have been conducted with a plastic microplate and which have necessitated many reaction and culture steps in the prior art. The test kit of the present invention can be produced at an extremely low cost because of its structure. The test kit can previously contain a reagent necessitated for the test to remarkably facilitate the test.
