Packaging is evolving as brands seek safer, lighter, and more efficient ways to transport liquids and semi-liquids. Among flexible containers, the CUBITAINER® has become widely used across food, chemical, cosmetic, and laboratory industries thanks to its durable, collapsible design and compatibility with many dispensers—making it a strong alternative to rigid bottles and jerry cans.

What Exactly Is a CUBITAINER?

A CUBITAINER is a collapsible, cube-shaped liquid container typically made from low-density polyethylene (LDPE). It is designed to hold a wide range of liquids—food-grade ingredients, chemicals, reagents, cleaning solutions, oils, and beverages—while offering superior flexibility and lightweight handling.

It consists of two main components:

• Inner LDPE Cubic Bottle (Flexible Structure)
• Outer Corrugated Box or Support Carton (Rigid Protection)

The inner bottle collapses gradually as the liquid is dispensed. This collapse prevents air from entering the container, thereby reducing oxidation, product contamination, and waste.

CUBITAINERS were originally developed as an alternative to rigid HDPE bottles, offering the same stability but with far better dispensing control, storage efficiency, and environmental benefits.

Structural Features of a CUBITAINER

The design of a CUBITAINER is highly engineered to ensure durability, collapsibility, and leak prevention. Its structure includes:

LDPE Flexible Container

• High-clarity LDPE allows product visibility
• Semi-rigid but collapsible walls
• Smooth interior for full product evacuation
• Compatible with many food- and chemical-grade liquids
• Lightweight and odor-free

Molded Handles

• Built-in ergonomic handles
• Easier pouring and transportation
• Reduced risk of user spillage

Tamper-Evident Spouts & Caps

• Available in different diameters
• Prevent leakage during transportation
• Support pump heads, taps, and dispensing valves

Outer Corrugated Box

• Often made of strong kraft corrugated board
• Provides stacking strength
• Adsorbs impact to protect the LDPE bottle
• Optional branding, printing, and color customization

Why Choose CUBITAINER? Key Advantages

Manufacturers choose CUBITAINER because it combines the advantages of rigid containers with the convenience of flexible packaging. Its benefits include:

Space Efficiency

• Cube shape optimizes pallet loading
• Nested shipping (collapsed) reduces freight cost by up to 50% compared with rigid jerry cans
• Lightweight, lowering total transport weight

Exceptional Product Protection

• No air ingress during dispensing
• Hygienic sealed system
• Ideal for oxygen-sensitive liquids like beverages, oils, or chemicals

Sustainable & Low Waste

• Uses less plastic than rigid HDPE containers
• Fully recyclable LDPE
• Outer boxes are recyclable paperboard

Versatile and User-Friendly

• Compatible with manual taps, pump dispensers, and filling lines
• Easy to carry
• Suitable for controlled dosing

Cost-Effective Storage & Shipping

• Collapsible design reduces warehouse volume
• Lower shipping cost
• Reduced breakage compared with glass or hard plastic

Typical Sizes of CUBITAINER

Most suppliers offer from 1 liter to 20 liters, though custom sizes exist.

Common CUBITAINER Sizes & Their Typical Uses

Capacity	Typical Use Cases	Notes
1–2 L	Laboratory chemicals, cosmetics, and pharmaceutical reagents	Easy manual dispensing
3–5 L	Food sauces, oils, syrups, and cleaning detergents	Most popular size
10 L	Beverage syrups, industrial solvents	Great cost-to-volume balance
18–20 L	Bulk chemicals, sanitizers, automotive liquids	Replaces 20L HDPE jerry cans

CUBITAINER vs Bag-in-Box vs Jerry Can

To understand where CUBITAINER excels, it’s useful to compare it with other packaging systems.

CUBITAINER Comparison with Other Common Liquid Containers

Feature	CUBITAINER	Bag-in-Box (BIB)	HDPE Jerry Can
Plastic Usage	Medium	Low	High
Recyclability	High	Medium	High
Air-Tight Dispensing	Excellent	Very Good	Poor
Structure	Semi-rigid cubic bottle	Flexible inner bag + box	Fully rigid HDPE
Storage Efficiency	High	High	Low
Transportation Cost	Low	Low	High
Best For	Chemicals, food, cosmetics	Beverages, syrups	Oils, agrochemicals

Summary:
CUBITAINER sits between rigid jerry cans and bag-in-box. It is more durable and easier to handle than BIB, yet uses less plastic and space than jerry cans.

What Products Are Commonly Packed in CUBITAINER?

How CUBITAINERS Are Manufactured

The inner LDPE bottle is typically made using a blow-molding process, while the corrugated box is designed to match the exact bottle dimensions for stability.

Manufacturing Steps

• LDPE Granules Melting
• Extrusion Blow Molding into Cube Shape
• Cooling & Wall Thickness Calibration
• Neck & Handle Molding
• Leak Testing & Sterilization (for food/medical use)
• Outer Carton Printing & Die-Cutting
• Assembly, Packing, and Shipment

High-quality suppliers also offer gamma sterilization for sensitive industries like pharmaceuticals and biotechnology.

How to Use CUBITAINER in Production Lines

CUBITAINERS can be used in both manual and automated lines:

Manual Filling

• Small manufacturers often use gravity filling
• The bottle remains inside the exterior box during filling

Automatic Filling Lines

Compatible with:

• Peristaltic pump fillers
• Overflow or volumetric fillers
• Chemical filling lines
• Food-grade aseptic lines

Dispensing

CUBITAINERS can be used with:

• Dispensing taps
• Spray pump attachments
• Automated dosing pumps
• Tube extraction systems

This makes them ideal for industrial production and retail dispensing.
