JPH0285182A - Deodorizing and freshness keeping bag - Google Patents

Abstract

PURPOSE:To adsorb bad odor and not to release it to the outside by making the inner side of a bag a layer in which a high density adsorbent is kneaded and the outer side a layer in which a low density adsorbent is kneaded or a layer of a resin alone, and sealing the bag with a zipper which is attached at the opening. CONSTITUTION:Using a polyethylene resin 4, in which a high density adsorbent is kneaded, for the inner layer, and a polyethylene resin, in which no adsorbent is added, for the outer layer, an inflation film is formed. The film is made into a bag shape 1, and the bag is sealed by installing a zipper 2 at the opening. When raw trash is placed in this bag, and the bag is sealed by the zipper, the odor is not sensed outside.

Description

[Detailed description of the invention] (Industrial application field) You can.

(Conventional technology) There wasn't.

(Problem to be solved by the invention) It is not effective when used as intended.

(Means for solving the problem) A high-concentration adsorbent is kneaded inside, and a low-concentration or resin-only layer is formed on the outside. By attaching the zipper to the mouth and sealing it, the absorbent layer inside the bag will not absorb unnecessary gas.

(Function) A layer with a low concentration of adsorbent or no additives increases resistance to tearing and improves airtightness.Also, since a high concentration of adsorbent can be placed inside, the adsorption capacity can be increased.

By attaching a sealing chuck to the gas-barrier outer layer and mouth, it is possible to extend the storage time of the inner layer adsorbent. Also, if you put something that emits a foul odor into this bag, the airtightness and adsorption action will prevent the foul odor from leaking to the outside. In this way, a deodorizing bag that has a high ability to adsorb dirt, is easy to store before use, can be stored for a long period of time, and has little leakage of bad odors to the outside even when in use becomes a deodorizing bag. For the same reason, vegetables,
The bag can be easily stored as a bag for keeping fruits fresh, and it prevents ethylene gas from leaking from inside the bag and entering from the outside, making it easy to store even when different types of vegetables and fruits are stored in the same place. Freshness can be maintained without being affected by each other.

(Example) A blown film was created using a polyethylene resin mixed with zeolite adsorbent at a weight ratio of 6% for the inner layer and a polyethylene resin with no adsorbent added for the outer layer.The film was made into a bag shape and a zipper was attached to the opening. can be attached and sealed. In the structured bag, each layer has a thickness of 50 B, and the size is 400 mm in width and 300 mm in width, with a total thickness of 100 μm. Garbage was put in the container, sealed with a zipper, and left for one day, but no odor was detected outside.

Claims (1)

[Claims] In a bag that has a zipper for the purpose of sealing the inside of an opening made of a multilayer film, a gas adsorbent suitable for the purpose of adsorbing gas is kneaded into the synthetic resin that makes up at least one layer of the multilayer film, and At least one layer of the bag is made of synthetic resin with good gas tightness.
