What kind of transparent disposable beverage cups work for your business? PLA and PET cups are currently the most popular in the market. But many people have trouble distinguishing them. But many people have trouble telling them apart. Today, Hydepackage will help you thoroughly explain the differences between PLA cups and PET cups. After reading this, you will know which one to choose.

What exactly is the PLA Cup?

The PLA cup is made from polylactic acid from plants such as corn and sugar cane. It is not a conventional plastic but rather a biodegradable and compostable environmental friendly material. Hence it is highly preferred for packaging of eco-friendly cold drinks.

Hold it in your hand and the PLA cup is transparent and looks like traditional plastic cups. It is quite transparent and suitable for holding milk tea, juice, cold brew coffee, salads, smoothies, and cold drinks for delivery.

The PET cup is constructed from polyethylene terephthalate, the same clear plastic cup we are most familiar with. The benefits are very obvious. High transparency, good toughness, stable price and good leakproof performance.

What is a PET cup?

The PET cup is made of polyethylene terephthalate - the same transparent plastic cup that we are most familiar with. The benefits are very clear: high transparency, good toughness, stable price and good leak-proof performance.

The bubble drinks, iced coffees, milk teas, fruit cups and salad boxes that we usually consume are mostly in PET cups. This is because the PET technology is mature and the supply chain is stable. In the market where large quantities are purchased, it still holds a very important position.

What exactly is the difference between PLA cups and PET cups?

Let's directly address the points that you are most concerned about.

1. Environmental performance

PLA Cup: Raw material is renewable, can be composted. If your company cares about ESG and is looking to get environmental certification or if you want to help reduce plastic pollution then PLA is clearly more aligned with this direction.

PET Cup: It’s still traditional plastic in essence, but it’s recyclable. If most of your customers are in regions with strict environmental policies such as Europe and the US, then PLA will be a better fit with the market trends.

2. Temperature resistance performance

PET cup: It has better stability and is suitable for most cold drink scenarios. It also doesn't deform easily during transportation.

PLA cup: It is mainly suitable for cold drinks. Don't put hot drinks in it because the cup body may become soft when the temperature is high.

3. Cost Variance

Currently, the overall cost of PET cups is generally lower than that of PLA cups. For a big chain restaurant or one that’s going to do a large volume of takeout, PET can still be a cost advantage. However, with more and more people paying attention to environmental protection, many brands are also willing to spend a little more money to switch to PLA.

4. Trends in the Market

Recently, more and more consumers in Europe and the USA have chosen environmentally friendly packaging. In many coffee shops, tea brands and chain restaurants PET is slowly being replaced by PLA.

So how choose?

This is an easy way for you to judge.

If your bigger concern is the environmental brand image, sustainable packaging and compliance with future environmental regulations then choose PLA cups. In the end it will be a better choice.

If you are focused on the cost of large-scale procurement, transparency display effects, the stability of supply chains, and the regularity of cold drinks, then PET cups are still a mature and cost-effective choice.
