5 Things You Need to Know about our HPDE Containers

Class Plastics’ HDPE containers are specially designed for ease of transport with an increased packing capacity of up to 25% compared to other conventional containers. Other optional features include the “anti-glug neck”, for safe and quick pouring, and the “mono-layer barrier technology” from Baritainer to reduce permeability.

HDPE (High-Density Polyethylene) is one of the most widely used materials for liquid packaging containers. It is suitable for a diverse range of products including agricultural chemicals, lubricants, acids, chlorine, flavor and ingredients, and other general chemicals.

HDPE is a cost-effective alternative to metal and other flexible packaging containers.

But while it is considered as a common commodity when it comes to plastic containers, a lot of people still shy away from using HDPE, particularly because these containers are very large and bulky. They take up a lot of space during transport, and then there are recyclability issues and other limitations of HDPE.

What you need to know about Class Plastics HDPE containers

For over 25 years, Class Plastics has been an industry leader in manufacturing and delivering HDPE packaging containers.

We have put together this list to help you know more about HDPE and how we are continuously innovating our HDPE containers to meet our customers’ existing and future needs.

1. Specially designed for transport efficiency

Australia in terms of its geography is very large and relies heavily on transport. One of the biggest risks when transporting liquid is the container falling off the pallet. If the container leaks or spills, you end up with product loss and the cost of clean up.

Class Plastics’ HDPE containers are specially designed to maximise transport efficiency.

Compared to a generic cube with a 16 per layer footprint , our rectangular container with a 20 per layer footprint has an increased capacity of up to 25%, but takes up the same amount of floorspace per square metre during freight.

A customer who recently converted from the generic 16 per layer footprint to the rectangular 20 per layer footprint was able to increase their product output because they are now able to ship more of their products.

Our HDPE containers’ interclock stacking system also allows you stack the containers up to two containers high in the pallet.

The recommended height when stacking the containers is up to two containers high. The resin used to make the containers has a high elastic component that allows the containers to expand and contract in normal and heated temperatures. Stacking more increases the weight and reduces the elasticity, and because of this the containers may crush or fall off.

2. Lightweight yet extremely strong

Class Plastics’ HDPE containers are lightweight yet extremely strong. They come in manageable and smaller pack sizes for easy carrying and quick pouring.

Contrary to a common misconception that HDPE can onlywithstand certain load weight, Class Plastics containers have much thicker walls compared to its traditional counterparts that resist impact and provide a good moisture barrier. The containers can also withstand temperatures of up to 30 to 40 degrees when in storage.

The containers are also shrink wrapped to prevent them from contracting dust and dirt while in storage or transport.

3. 3 product features in one

Class Plastics HDPE containers are designed to give ultimate value to our customers.

You have can have all 3 of our key product features in one HDPE container.

  • Increased capacity of up to 25%
  • Anti-Glug Pouring system that enables smooth continuous flow of liquid, reduces spills and unnecessary wastes.
  • Barrier Technology that makes the containers more resistant to liquids being able to permeate into and through the plastic.

4. Recyclable and environment friendly

HDPE is by far one of the easiest plastic to recycle. Its resin code identification number is “2”.

Class Plastics manufacture fully recyclable HDPE containers, and the containers can be reused for products of the same family. They are suitable for a wide range of products including agricultural chemicals, industrial chemicals, lubricants, flavors and ingredients, and other general chemicals.

5. Bungs

Why tighten the bungs?

A large percentage of our containers have a hole punched and a bung that seals the hole.

Plastic shrinks when cooling. While the plastic cools down, the bung area shrinks down. The bungs eliminate leaking containers.

We fit the bungs into this area to make sure that there is no air leaking. The bungs are fitted to the containers at around 50 to 69 degrees. At that temperature, the bung cannot be fully tightened because it will dethread. Upon delivery, customers should tighten the bungs to create a liquid seal.


Class Plastics offer a vast range of HDPE containers from generic cubes, jerry cans, rectangular and hexagon containers in 1- to 1000L capacities, as well as accessories. All of our products use food grade resin and are FDA and DG (dangerous goods) approved.

We have established a nationwide distribution network to satisfy our customers’ delivery needs. Whether you are in the city, the suburb or the next state, Class Plastics will make sure that your containers are delivered on time.
