It is a high-function film which integrates a film and desiccant.

Features of Moisture Absorption Film

FEATURE

The many benefits of Moisture Absorption Film

01

Prevents deterioration of the contents' quality caused by moisture without desiccant.

02

05

Considered as eco friendly packaging by eliminating use of desiccant (desiccant + its outer film).

Functions of Moisture Absorption Film

FUNCTION

01

Keeps inside the pouch at a low humidity.

Moisture absorption speed comparison

Condition : Place a 100mm X 100mm test sample of MARUTO Moisture Absorption Film in a temperature and humidity testing chamber and then measure the increased weight (the moisture absorption volume) of the film after each time interval and conduct a calculation using the proportion.

02

Compared to desiccants, it has a more stable moisture absorption effect and does not evaporate (discharge) moisture even under high temperature conditions.

Moisture Absorption Film -

【1】
absorbs moisture by chemical reaction, so moisture once absorbed will not be evaporated (discharged) even under high temperature conditions.
【2】
protects the contents from the risk of moisture evaporation (discharge) from the desiccant when the bag is exposed to high temperature conditions, such as container while ocean freight or warehouse in summer, which may cause damage to the contents.

Condition : After 48h of measurement at 40℃-90%RH from the initial stage to moisture absorption, measurement at 70℃ for 48h in a temperature-controlled chamber after moisture absorption. (96 hours in total)

The film itself absorbs moisture, so it enables drying with less unevenness.
Even under high temperature conditions, it will not evaporate (discharge) moisture once it has absorbed moisture. (Irreversible reaction)

03

Versatility that can be added to a variety of applications and pouch shapes.

Moisture Absorption Film is optimal for products where there are concerns about quality deterioration due to moisture.

Categories most likely to be effective

Health foods and drugs

Health foods and drugs

Products where moisture changes the composition

Example) Vitamin, collagen, etc.

Electronic components

Electronic components

Products where uniform moisture absorption is required. Products where variation in the amount of drying is a problem

Foods

(water activity less than 0.6Aw)

Products where moisture changes the taste, or changes the color
Example) Coffee, tea, powdered seasoning, etc.

Voice from customers

CUSTOMER VOICE

We received several complaints from customers a few times a year about accidental ingestion and omission of desiccants. When we were wondering what we could do to solve this problem, we got a suggestion of "Moisture Absorption Film". By using this film, we don't have to use desiccant, so we don't have any more complaints about desiccant.

The story behind the development of Moisture Absorption Film

EPISODE01

Moisture Absorption Film absorbs moisture in the pouch without the need for desiccants. It is now used in a variety of applications such as food, health food, medicine, and electronic parts. In fact, the idea for Moisture Absorption Film came from one of our customer's idea.

EPISODE02

It was around 2010. We worked with a customer who was a long-established soy sauce manufacturer in Fukuoka. The customer was selling soup stock packs made from their special ingredients. The soup stock packs became popular, and quickly gained a reputation as " the soup stock packs allow you to enjoy the taste of professional soup stock at home." The product became a hit, and selling several hundreds of thousands of bags a year.

EPISODE03

Even after the product started selling steadily every year, the customer was troubled by a problem. It was "accidental ingestion of desiccant". Not often, but once a year or so, a consumer would accidentally boil the enclosed desiccant and eat it by mistake.

EPISODE04

The warning is clearly written on both the package and the desiccant that the desiccant is inedible, and the incidence of occurrence is 0.001% per year. It was thought that it would be difficult to eliminate this incidence completely. Even so, we had to reduce the number of problems caused by desiccants to zero. This was the mission conveyed to us by the customer.

EPISODE05

With the customer's strong feeling that "we don't want consumer to feel this way even if it is only one in a million from who buys our products", we sympathized and started working.

EPISODE06

The only way to eliminate the accidental ingestion of desiccants was to put a function on the package that would not require desiccants. This was a difficult challenge. Thus, after much trial and error, Moisture Absorption Film was developed.

EPISODE07

Even if it is just a small voice, " We want to eliminate the accidental ingestion of desiccants", this thought led to the development of desiccant-free Moisture Absorption Film. Today, we receive millions of orders for Moisture absorption bags every year, and you may be using it in your home. Our mission is to contribute to the enrichment of human life.
