したものである。Conventionally, packaging materials for photosensitive materials have been high-pressure branched low-density polyethylene (hereinafter LDPE) mixed with carbon black.
A composite laminate film made by laminating a resin film or LDPE resin film, paper, and aluminum foil was used. For example, as shown in FIG. 15, an aluminum foil 6 and a flexible sheet layer 5 are laminated with an adhesive layer 4 between LDPE resin films N2a and 2a containing a light-shielding substance.

The present inventor has already proposed a laminated film in which an LDPE resin film containing at least one of a light-shielding substance and an antistatic agent is laminated on a cross-laminated film using a resin film (displayed as PE) (Represented by Utility Model Co., Ltd. −
19087). Furthermore, a packaging material having an inexpensive loss-laminated film with improved heat-sealability and light-shielding properties was also proposed (Japanese Utility Model Publication No. 61-20590).

。Furthermore, as a packaging material that has high physical strength, excellent heat-sealability, and is inexpensive, a film layer consisting of a resin composition in which carbon black is added to linear low-density polyethylene (hereinafter referred to as L-LDPE) resin is used. proposed a packaging material made of laminated film (Japanese Unexamined Patent Publication No. 1983-1989).

ことが試みられている。Since this transparent film has a high heat-sealable temperature and a narrow applicable temperature range, attempts have been made to improve heat-sealability by adding ethylene-polypropylene copolymer resin or the like.

保することが困難であった。The conventional laminated film containing the LDPE resin film has low physical strength (tear strength, etc.) despite its large thickness, is expensive, has poor heat sealability, and is prone to holes during packaging and transportation. It was difficult to ensure light-shielding, moisture-proofing, and gas barrier properties due to cracking, tearing, and peeling of the heat seal.

The packaging material having the cross-laminated film proposed in Publication No. 90 greatly improves physical strength such as tear strength and tensile strength, so it is excellent as a packaging material for heavy substances, and was put into practical use until recently. However, since a uniaxially stretched high-density polyethylene resin film is used for the heat-sealing layer, the heat-sealability is poor, and physical strength deteriorates due to variations in the thickness of the adhesive layer and the stretching ratio of the uniaxially stretched high-density polyethylene resin film, resulting in large curls. Occasionally, it would peel off or tear.

な積層フィルムになっていた。Furthermore, a cross-laminated film in which a vertically stretched film and a horizontally stretched film are laminated so that their stretching axes intersect requires the use of two types of film forming machines, resulting in an expensive laminated film.

The packaging material proposed in Publication No. 47, which has a light-shielding film using a resin composition in which carbon black is added to L-LDPE resin, is inexpensive, has good heat sealability, and has excellent tear strength and impact puncture strength. , it is very excellent as a packaging material for photosensitive materials.

た。However, when packaging heavy products or photosensitive materials with sharp edges, the Young's modulus is small, so holes and tears do not occur in the L-LDPE resin light-shielding film, but it becomes stretched and becomes thinner, and the light-shielding and moisture-proofing properties are insufficient. There were times when it was not possible to secure

Although physical strength such as tear strength has been improved, packaging materials in which an L-LDPE resin film layer containing a light-shielding substance is laminated on only one side of a metallized film have increased curling.

った。Transparent films made by adding ethylene-propylene copolymer resin, etc. to crystalline polypropylene (hereinafter referred to as PP) resin have improved heat-sealability to some extent, but have poor surface slippage and are difficult to use when using light-shielding substances such as carbon black. The light-shielding film containing the compound had poor physical strength, heat sealability, etc., and could not be put to practical use as a packaging material for photosensitive materials.

速度が遅いため、バブルが不安定になり、シワやブロン
キングが発生し易かった。Further, although the L-LDPE resin film has excellent tear strength, impact puncture strength, heat sealability, etc., the crystallization speed is slow, so bubbles become unstable and wrinkles and bronking are likely to occur.
ＰＰ樹脂フィルムは、引裂き強度が小さく、ヒートシー

を得ることができる。It is also preferable to mix two or more types of light shielding substances according to the required characteristics. For example, it is a mixture of a thin plate-like light-shielding material and a granular or spherical light-shielding material. In this case, carbon black with an average particle size of 200 rnIJ or less is added at 0.5 g/m per unit area of the packaging material <rr',
It is preferable to contain 2 to 50 g/rrT in order to ensure light-shielding properties. On the other hand, among these carbon blacks, those having a pH of 5 to 9 and an average particle size of 10 to 120111 microns are preferable, and furnace carbon blacks having a pH of 6 to 9 and an average particle size of 50 or less are particularly preferable. By using particles with such pH and particle size, there is less fogging, less increase and decrease in photosensitivity, greater light shielding ability, and no pinholes caused by carbon black lumps, fish eyes, etc. It is possible to obtain a packaging material that has a number of advantages such as improved physical strength and improved heat-sealing properties that are less likely to occur.

る。In particular, it is preferable to use it as an aluminum paste masterbatch resin in order to eliminate adverse effects on photographic materials and odor. For example, even if the mineral spirit content in a masterbatch resin with an aluminum paste content of 40% by weight is 1.0% by weight, if you try to make the aluminum paste concentration in the film layer 2% by weight, the aluminum 19 parts by weight of natural resin is kneaded with 1 part by weight of paste masterbatch. Since some of it is removed, the mineral spirit content is less than 0.05% by weight. As a result, there is no adverse effect on the photographic material, and odor is also reduced.
