If the number average particle size is smaller than the above range, the deodorant is likely to aggregate, and if the maximum particle size or the number average particle size is larger than the above range, the film has a film thickness or layer thickness of 20 μm or less. Particles larger than the thickness or layer thickness tend to be present and the homogeneity tends to be inferior, the deodorizing performance tends to be deteriorated, and the self-adhesiveness tends to be lowered.

粘着層は消臭積層体の少なくとも片側の表面層に設けることが好ましい。
[Adhesive layer]
The adhesive layer does not need to be provided when the deodorant laminate does not require self-adhesiveness or when another layer such as a layer containing a deodorant has sufficient self-adhesiveness. When the deodorant laminate, which is a layer, has self-adhesiveness, the deodorant laminate may contain an adhesive resin in a layer containing a deodorant, but a layer containing a deodorant. When sufficient self-adhesiveness cannot be exhibited due to the high concentration of the deodorant inside, it is possible to have an adhesive layer containing an adhesive resin but not containing a deodorant. By not containing a powdery deodorant, excellent self-adhesiveness can be exhibited.
The adhesive layer is preferably provided on the surface layer on at least one side of the deodorant laminate.

×：容易には剥離できなかった。
[Self-adhesive]
(Adhesive force in shearing direction)
Two laminated bodies were cut into 100 mm (machine traveling direction / hereinafter MD direction) × 50 mm, and the same surfaces were overlapped with each other facing each other, and the upper and lower films were further shifted by 50 mm in the MD direction.
Next, the non-overlapping length 50 mm × width 50 mm portion of each of the upper and lower laminates is used as a non-crimping portion, and the overlapping length 50 mm × width 50 mm portion is used as a crimping portion, and 0.18 MP with a blocking hand tester. A test piece was prepared by allowing it to stand at 40 ° C. for 12 hours under pressure and crimping it, and then cutting it into a width of 15 mm.
Then, the non-crimped portion was sandwiched between the pulling tester one by one, and pulled in the MD direction at a speed of 300 mm / min, and the shear peeling strength was measured.
A case where the adhesive strength was 1.5 N / 15 mm or more was regarded as acceptable.
(Vertical peelability)
Using a test piece prepared for measuring the adhesive strength in the shearing direction, one side of the stacked laminates was attached and fixed on a table, and the end of the non-crimped portion of the upper laminate was vertical. It was lifted up and peeled off, and the ease of peeling was sensory evaluated according to the following evaluation criteria.
◯; It could be easily peeled off.
X: It could not be easily peeled off.
［製袋性（ヒートシール性）］
４０ｃｍ×２０ｃｍの２枚の積層体を、消臭粘着層同士が対向するように重ねて、４方をヒートシールしてパウチ袋を作製し、下記合否判定基準で評価した。
ヒートシール条件
温度：１８０℃
圧力：１ｋｇｆ／ｃｍ2
時間：１秒
合否判定
○：問題無く製袋できた。
×：製袋できなかった。
[Bag making (heat sealing)]
Two 40 cm × 20 cm laminates were stacked so that the deodorant adhesive layers face each other, and heat-sealed on four sides to prepare a pouch bag, which was evaluated according to the following pass / fail criteria.
Heat seal condition Temperature: 180 ° C
Pressure: 1 kgf / cm 2
Time: 1 second Pass / Fail Judgment ○: The bag was made without any problem.
X: The bag could not be made.
［消臭性］
作製した積層体を用いて１２０ｍｍ×１６０ｍｍの大きさの四方パウチ袋からなる内袋用小パウチ袋を２個作製し、１個の内袋用小パウチ袋の内部には３００ｃｃの硫化水素ガス（２４ｐｐｍ）を充填し、もう１個の内袋用小パウチ袋の内部には３００ｃｃのアンモニアガス（７５ｐｐｍ）を充填した。
次に、１９０×１５０ｍｍの大きさの四方パウチ（ジーエルサイエンス株式会社製ＰＡバッグ使用）からなる外袋用の大パウチ袋を２個用意し、１個の大パウチ袋の内部には上記の硫化水素ガスを充填した内袋用小パウチ袋を封入し、もう１個の大パウチ袋の内部にはアンモニアガスを充填した内袋用小パウチ袋を封入した。
そして、２個それぞれにおいて、外袋と内袋の間の空間が、１００ｃｃになるように、空気を充填して調節し、２日間２５℃で放置後に外袋と内袋の間の空間の空気を採取して、硫化水素ガスまたはアンモニアガスの濃度を測定した。
[Deodorant]
Using the prepared laminate, two small pouch bags for inner bags consisting of four-sided pouch bags with a size of 120 mm × 160 mm were prepared, and 300 cc of hydrogen sulfide gas (300 cc of hydrogen sulfide gas) was produced inside one small pouch bag for inner bags. 24 ppm) was filled, and 300 cc of ammonia gas (75 ppm) was filled inside the other small pouch bag for the inner bag.
Next, prepare two large pouch bags for outer bags consisting of a square pouch with a size of 190 x 150 mm (using a PA bag manufactured by GL Science Co., Ltd.), and inside one large pouch bag, the above-mentioned hydrogen sulfide is used. A small pouch bag for an inner bag filled with hydrogen gas was sealed, and a small pouch bag for an inner bag filled with ammonia gas was sealed inside another large pouch bag.
Then, in each of the two pieces, the space between the outer bag and the inner bag is adjusted by filling with air so as to be 100 cc, and after leaving at 25 ° C. for 2 days, the air in the space between the outer bag and the inner bag is adjusted. Was collected and the concentration of hydrogen sulfide gas or ammonia gas was measured.
