改善された耐水性ないし防湿防錆性の包装材料に
係る。[Detailed Description of the Invention] The present invention relates to a water-resistant, moisture-proof and rust-proof packaging material with improved curling properties for packaging foods, machinery, etc.

いる。 Traditionally, polyethylene sheets approximately 100μ thick have been used to package plant machinery, electrical products, etc. to prevent surface damage to the machinery, or composite sheets containing aluminum foil have been used to protect machinery from moisture.
Rust-proof packaging is applied. However, polyethylene sheets have relatively high moisture permeability (5 to 7 per 100μ).
g/m 2 /24 hours), lacks moisture-proofing effect and is not water resistant. Moreover, if rust prevention is required, a large amount of rust preventive agent (such as silica gel) is used, so it is difficult to say that it is an inexpensive packaging material. Furthermore, it has been pointed out that this sheet is weak in tension and has low resistance to protrusions, making it prone to breakage when machinery is packed and transported by wheel.

観点からも材料の効率的な使用法とはいえない。 In addition, composite sheets containing aluminum foil have relatively high moisture permeability because the aluminum foil itself has pinholes (for example, a composite sheet with a thickness of 7 μm has a
g/m 2 /24 hours, 2 to 5 g/m for 9μ thick
m 2 /24 hours). Moreover, since aluminum foil lacks flexibility, pinholes occur frequently when wrinkles or folds occur in the composite sheet. It is virtually impossible to cover machinery with complex shapes with a composite sheet without wrinkles or creases, and by making the composite sheet thicker by including aluminum foil, strength and moisture resistance can be maintained. However, it cannot be said to be an efficient method of using materials from the perspective of resource conservation.

が要求されている。 Japanese Utility Model Publication No. 54-85176 discloses a moisture-proof packaging material made of a polyester film on which aluminum is vapor-deposited on reinforced canvas cloth. This packaging material has excellent mechanical strength and is highly moisture-proof (overall
Moisture permeability is 0.2-0.3g/ m2 /24 with a thickness of about 100μ
time). However, packaging materials with even higher moisture-proofing effects are required.
そこで、本考案者はアルミニウム蒸着フイルム
を使用してピンホールの殆どない積層シートを検
討した結果、本考案の改良技術を見い出したもの
である。 Therefore, the present inventor investigated a laminated sheet with almost no pinholes using aluminum vapor-deposited film, and as a result, discovered the improved technology of the present invention.

A sheet-like packaging material consisting of a laminate having an aluminum vapor deposited layer 14 on one side, a polyethylene film 12 on top of that, a polyester film 10 on top of that, and a polyethylene film 12 on the other side of the film 16. It is.
本考案を説明する。 The present invention will be explained.

好ましくない。 The polyester films 10 and 16 are preferably biaxially stretched and heat-set films made of polyester such as polyethylene terephthalate or polybutylene terephthalate, and have a thickness of about 8 to 20 microns. Biaxially stretched films are strong and highly flexible, and can be easily deposited with aluminum. If the film has a thickness exceeding 20 μm, it will be too rigid as a packaging material, and the aluminum vapor-deposited surface will easily break and peel off when bent, and the workability of bag processing will also deteriorate. Furthermore, a film that is too thin is not preferable because it reduces mechanical strength and weather resistance.

を構成する際の接着力が高い利点がある。 The aluminum evaporated layer 14 is formed on one surface of the polyester film 16 by vacuum evaporation or a combination of sputtering and evaporation, and its thickness is usually about 600 Å. A polyester film coated with aluminum vapor deposition has a better moisture-proofing effect than a laminated sheet of aluminum foil and polyester film. This is because the aluminum vapor deposited layer, although thin, has pinholes and is less likely to generate pinholes due to use. The aluminum vapor-deposited layer has the advantage of having a moisture-proofing effect and high adhesive strength when forming a laminate.

が雨水等の防水効果はある。 In the present invention, a polyethylene film layer is formed on the vapor deposition layer, and this polyethylene film layer (inner polyethylene film layer) is bonded by melt extrusion method to bond polyethylene onto the vapor deposition layer of the vapor-deposited polyester film. (laminate)
It can be formed by a method of bonding a film in advance to a vapor deposited film via an adhesive. This polyethylene film layer is 25~
The thickness is preferably about 50μ, more preferably about 25 to 40μ. A sheet of hydrophobic polyethylene with a thickness of 30μ has a water permeability of about 16 g/m 2 /24 hours, and although the water permeability is low, it is effective in waterproofing rainwater and the like.

料全体としての可撓性が欠ける。 Further, the polyethylene film layer (outer polyethylene film layer) provided on the other surface of the polyester film 16 can be provided by the same method as the method for forming the inner polyethylene film layer. By providing this polyethylene film layer, curling of the packaging material can be prevented, and heat-sealability can be imparted to the packaging material. Furthermore, by making the outer polyethylene film layer slightly thicker than the inner polyethylene film layer, curling of the laminate can be further suppressed and improved. The outer polyethylene film layer preferably has a thickness of about 25 to 50 microns, more preferably about 30 to 50 microns. If the thickness of both the inner and outer polyethylene film layers exceeds 50μ, the packaging material as a whole will lack flexibility.

包装において、本考案の包装材料を連結接合して
大きな面積を有するシートとし得ること、間隙の
ないように重ね合せ部分を融着せしめることがで
きる点である。 One of the main functions of this outer polyethylene film layer, as mentioned above, is that it is highly thermoplastic and has heat-sealing properties, which makes it possible to connect and bond the packaging material of the present invention in the packaging of very large machines. The advantages are that it can be made into a sheet having a large area, and that the overlapping portions can be fused together without any gaps.
本考案の複合シートからなる包装材料はピンホ

効果も有しているから、食品・精密機械・電気製
品の包装材料として特に望ましい。 The packaging material made of the composite sheet of this invention does not have pinholes, so its moisture permeability is 0.2g/m 2 /24
It takes less than an hour and has extremely excellent moisture-proofing and rust-proofing properties. Furthermore, since the outermost coating layer of the polyethylene film has heat-sealability, workability during packaging is improved. Furthermore, the vapor-deposited layer has the effect of blocking ultraviolet rays and radiant heat, and also has the effect of preventing the adhesion of dust due to static electricity generated on polyester films and polyethylene layers, so it is particularly desirable as a packaging material for foods, precision machinery, and electrical products.
なお、外層となるポリエステルフイルム層とし
ては、絹目のような微細な凹凸を賦与したエンボ
ス加工フイルム、添加物を加えて製膜して艶消し
処理を施したフイルムが好ましいものとなる。 As the polyester film layer serving as the outer layer, it is preferable to use an embossed film provided with fine grain-like irregularities, or a film formed by adding additives and subjected to a matte treatment.
本考案は粗布に替えてポリエステルフイルムを
使用している結果、耐水性や防湿効果が一層高め
られている。そして粗布のもつ表面凹凸を艶消し
ポリエステルフイルムとしたことにより光沢も眩
しくなく、耐候性も高められる利点がある。 This invention uses polyester film instead of sackcloth, resulting in even greater water resistance and moisture-proofing effects. By using a matte polyester film to replace the surface irregularities of sackcloth, there are advantages in that the gloss is not dazzling and weather resistance is also improved.
本考案の包装材料は、−60℃の低温に耐え、耐
油性・耐薬品性が優れている上に、防湿性が従来
品に比較して一段と優れ、薄手かつ軽量であり、
包装に際し防錆剤（シリカゲル等）の使用量が1/
１０〜1/20程度となる利点もある。 The packaging material of the present invention can withstand temperatures as low as -60°C, has excellent oil and chemical resistance, is even more moisture-proof than conventional products, and is thin and lightweight.
The amount of rust preventive agents (silica gel, etc.) used during packaging is reduced by 1/2.
There is also the advantage that it is about 10 to 1/20.
