Cheap, Waterproof Material able to withhold a Carbonated Liquid

[LG911]

Hi,

I am Design student at Brunel University London and was wondering if anyone could help.

One of my current projects is to design a cheap bottle/container to withhold a carbonated drink. The product must be extremely cheap as it is to be aimed at drink markets in such countries as Uganda.

I have some innovative ideas for Bottle design e.g. saving space during transport, and have also explored putting carbonated drinks into pouches (e.g. like Capri sun products)

Can anyone suggest any cheap, and relatively strong materials that could be used for these applications? Or point me in a direction?

Bottles are tested up to 8bar in pressure to give you an idea of the strength needed.

I have tried scrawling through the internet, and searched the University library for all kinds of materials and smart materials, but so far I’m having no luck.

Thank you in advance for any help.

Luke

Hello Luke,

I can offer some suggestions for materials that could potentially be used for your project. One option could be using PET (polyethylene terephthalate) plastic, which is commonly used for carbonated drink bottles due to its strength and durability. Another option could be using HDPE (high-density polyethylene) plastic, which is also strong and relatively cheap.

In terms of innovative designs, you could consider using biodegradable materials such as PLA (polylactic acid) or PHA (polyhydroxyalkanoates). These materials are not only strong and lightweight, but also environmentally friendly and could potentially appeal to the market in Uganda.

Additionally, you could explore using aluminum or steel for your bottle design. These materials are known for their strength and could potentially withstand the pressure of carbonated drinks.

I would also recommend reaching out to experts in the field of packaging and materials science for further guidance and advice. They may be able to provide more specific recommendations based on your project requirements.

Best of luck with your project!

Hello Luke,

I am a scientist and I would be happy to provide some suggestions for your project. First, I would recommend considering using PET plastic for your bottle design. PET is a strong and durable material that is commonly used for carbonated drink bottles. It is also relatively cheap and easy to manufacture.

Another option to consider is using aluminum for your container. Aluminum is lightweight, strong, and can easily withstand the pressure of carbonated drinks. It is also a widely used material in the beverage industry and can be produced at a low cost.

In terms of waterproofing, you could consider using a coating or sealant on the interior of the bottle or pouch to prevent any leakage of the carbonated liquid. Additionally, you could look into using biodegradable materials for your packaging to make it more sustainable and environmentally friendly.

I hope these suggestions are helpful and wish you success with your project. Keep exploring and experimenting with different materials to find the best solution for your design. Best of luck to you!
