About Products
Molded Liquid Container
Cubitainer®
Synonymous with "bag-in-box," the Cubitainer® is a liquid container which can replace rigid containers, including metal tins, plastic containers and pails. They have been manufactured and sold since 1964.
Cubitainer® is composed of a thin layer of plastic and a cardboard box. The standard type is a mono-material, providing a recyclable solution.
For oxygen sensitive products, we can add the appropriate gas barrier films as well.
Cubitainer® is produced worldwide in Japan, North America and Malaysia.

Film Liquid Containers
Z-tainer®
Z-tainer® is an alternative liquid container to rigid, plastic containers, metal containers, and pails.
Designed with safety in mind, the double structure bag-in-box features a gusset-shaped film based pouch.
Assembled to be inside of a cardboard box, this container’s oxygen barrier is a great solution for oxygen-sensitive contents.
For ease of handling, containers over 10L come with a handle hole (with exceptions).
The inner pouch can maximize content evacuation.
Product Features
| Gusset-shaped inner container | Inner container can stand on its own without external cardboard box |
|---|
This is ideal in order not to bring cardboard into cleaner areas of use.
| Handle hole for easier carrying | Handle is located at the top of the inner container |
|---|
Easy to carry by taking it out from the cardboard box.
| Minimizing residual liquid | These pouches have the same evacuation performance as the Cubitainer® |
|---|
Loss of precious contents reduced, thereby contributing to lower cost of ownership.
| Customizable film structures | Film structures that fit various needs |
|---|
By using optimal barrier films, shelf life can be extended and total cost of ownership reduced.
| Easy to automate filling | Easily fed into an automatic filling line |
|---|
This will ultimately reduce the number of people required to operate filling stations, which drives down total cost of ownership.
| Customize | We accommodate your requests |

Accessories
We have a wide variety of accessories which can be used for both Cubitainer®︎ and Z-tainer®
The following accessories can be used for both Cubitainer® and Z-tainer®
Disclaimer: These accessories are specifically designed for Cubitainer® and Z-tainer®. Please refrain from using them for other purposes.
SC CAP
Screw type cap that is one of the most versatile caps.
P CAP
Made of additive-free polyethylene.
DM CAP
Soft material ensures high sealability.
PGC CAP
Optimal for gas-producing liquids. Gas can easily pass outward but liquid is prevented from leaking out.
TAP-A
Enables opening and closing and allows controlled dispensing.
TAP-A NEO
Equipped with a handle stopper to prevent unwanted opening. Dispensing remains possible with the handle stopper attached.
TAP-B
Enables quick extraction of highly viscous contents.
ELBOW
Can be connected to the port mouth and facilitates stable liquid dispensing. Collapsible.
Long hose
Expandable hoses.
Product Advantages
Supply Capacity
Production volume of molding type is the highest among the industry. No 1 share in the world. Stable supply is possible.
BCP
Cubitainer® is supplied from multiple manufacturing locations.
Service
ZACROS’ technical staff are readily available to assist, and we can facilitate discussions with equipment manufacturers.
Waste Reduction
Cardboard is highly recyclable and the inner plastic container is made of 150g of resin, which is much less than rigid plastic containers.
Storage
Cubitainer® and Z-tainer® are packaged compactly which enables reduction of storing space.
Barrier Property
We can include barrier films such as EVOH into container film layers according to the product contents. We can help optimize the right barrier for the specific product.
Shielding from Light
Light shielding is provided by cardboard.
Used for hypochlorous acid water which is sensitive to light
Aesthetics
Decorative printing is possible on cardboard (with the use of coated cardboard) for mineral water, wine, etc.
Cleanliness
Inner containers can be taken out from the cardboard by the hanger hold and stand on their own. Therefore, you can take these out before entering cleaner areas to avoid generating extra particles.
Non Rusting
The inside surface is made of polyethylene which has high chemical resistance, making it compatible with many kinds of contents.
The exterior being corrugated cardboard means that unlike metal, it doesn't rust.
Easy to Fill
The Cubitainer® is easy to fill on semi-automatic machines with its unique shape retention, wheras the Z-tainer® is geared more towards automatic filling.
Dispensing
Various accessories help with ease of dispensing such as increasing fluid flow through preventing air displacement.
Easy Capping
The caps are designed to screw-on evenly, which helps avoid unintentional leaking.
Ease of Disposal
The containers can be separated and discarded each into their own category. Cardboard can be recycled, and inner containers only make up 150g of plastic waste.
Price
The cost of the containers varies with quantity purchased.
