About our products

The high-performance films manufactured by Oomori Kasei are required to have various characteristics depending on the packaging applications of our customers. In addition to strength and suitability in terms of safety and health, our film manufacturing will never stop evolving, including environmental compatibility in line with the growing environmental awareness worldwide.
With the unique production technology and relentless research and management system we have cultivated so far, we would like to develop packages with new functions with a spirit of challenging anything, in response to customer requests such as "I would like to use it for this purpose" or "Other companies refused because they said it was impossible."

Skin pack packaging film

This is a skin pack film that is sealed to the shape of the contents (product) and packaged in a vacuum. It is characterized by its high visual appeal, as it can convey the shape and texture of the product while still being packaged. It also contributes to reducing food waste and costs, as it extends the expiration date and does not require molds. This packaging material is supplied to a wide range of customers both in Japan and overseas.

Synthetic rubber block (bale) packaging film/melt bag

Our synthetic rubber block (bale) packaging film is manufactured in-house, with an integrated manufacturing system from film production to printing. Our products are used by many major synthetic rubber manufacturers, and we have a proven track record of over 30 years of quality and reliability. Some of our products are exported to Southeast Asia and as far away as Europe. Our melting bags are used by almost all domestic tire manufacturers, a great many rubber processing manufacturers, and overseas as well. Our melting bags, made from polybutadiene (RB), are available in three different types with different melting points.
SS type: 68°C, S type: 78°C, M type: 88°C (all representative values)

Applications

[Industrial materials] Synthetic rubber block (bale) packaging LDPE, EVA, alpha-olefin copolymer, EMMA
[Industrial materials] Melting bags for rubber chemicals Polybutadiene (RB), EVA

Polyethylene tube for packaging

These polyethylene tubes are used for bagging in manufacturers' automatic filling machines. They are manufactured with high precision, exceeding JIS standards, using dedicated machines and human know-how to ensure uniform thickness for automatic filling lines. Thorough quality control is ensured by repeated adjustments throughout the day in response to changes in air pressure and temperature. Oomori Kasei handles the entire process, from the production of film to packaging printing.

Applications

[Food packaging] For automatic packaging of powder, sugar, rice, etc. (paper bags, drum can inner bags) Contents: Powdered milk, glucose, etc.
[Industrial materials] For automatic packaging of sanitary products such as paper diapers

What is “bale” package ?

There is no waste generated and it does not put a strain on the environment.

Synthetic rubber block (bale) packaging film/melt bag

During the mixing process of synthetic rubber blocks (bales), the raw material for tires and other products, the packaging film can be kneaded and melted together with the rubber inside. Therefore, for packaging materials for synthetic rubber blocks, we manufacture film using controlled raw materials that will not be affected even if they are put into the mixing process together with the synthetic rubber. We also manufacture melting bags that melt at low temperatures as bags for various additives used in the rubber mixing process in tire manufacturing, rubber processing, etc. Both melt together, so the packaging material does not become waste.
Raw materials: Polybutadiene (RB), EVA, alpha-olefin copolymer, EMMA

An error of just 2mm!?

温度や湿度の変化にも対応して高品質を保つ。

包装用ポリエチレンチューブ

大森化成ではお客様の要望に合わせて、定められた規格(径や厚み)で誤差の少ない高品質なパッケージを生産しています。
気温や気圧の変化によって巾や厚みにバラツキが出やすいポリエチレンチューブですが、それを機械に精通した担当者が1日のうちで何度も調整しながら品質が均一になるよう管理。当社では径800㎜で長さ5000mのチューブの場合、その誤差はわずか2㎜以下という厳しい基準を設けています。

Multi-color printing for package films!

Accurate and speedy eight-color printing.

Flexographic Printing Machine

We have introduced a flexographic printing machine that is also used by major printing companies, and we carry out the entire manufacturing process up to printing. A reversing machine is installed, so we can accurately print eight colors on both sides of the tube, speeding up the process and reducing costs.
Unlike paper, the printing surface of the tube is soft and uneven, so it is possible to prevent misalignment of multi-color printing, which is a distinctive feature that significantly improves printing quality. In addition to film manufacturing, we can also finish printing at the same time.

You can even consult with us about difficult orders that other companies have rejected!

We will meet your needs with our experience and technology we have cultivated over many years.

Special Orders

Oomori Kasei employees love to try new things and take on new challenges. Please feel free to consult with us about special orders such as "Can you make a package with this material?" or "Can you make a package suitable for this purpose?" We have experience creating over 200 recipes to fulfill a customer's request. In one case, we introduced special equipment and built a new clean room. Starting from the customer's request, all of us are challenging ourselves to develop products that exceed expectations.

Challenge the possibilities of package!

We want to create a standard for the yet unseen future.

We also manufacture things that do not yet have a physical form.

We also accept consultations to consider packaging from the perspective of materials and uses, such as "We have this product..." or "We want you to consider the transportation method...". Oomori Kasei's manufacturing spirit is to challenge the possibilities of packaging. By utilizing the network of the Japan Packaging Institute, we would like to take responsibility and create things that we cannot do alone. Starting with a consultation, we want to create a standard for the yet unseen future. That is Oomori Kasei's passion.
