Thermoforming is changing because people want better materials. There is a move away from old plastics to new ones that help nature. Many companies now use starch-based bioplastics and other materials that can be renewed. These choices help the earth and make packaging safer.

Bioplastics in Thermoforming

Bioplastics have not taken over most regular plastics yet. Right now:

• Biodegradable polymers are only about 1% of all plastics.

You can find some types of bioplastics used in thermoforming. Each kind has good points and some problems.

Choosing bioplastics helps the earth in many ways:

• Some bioplastics break down on their own, so less trash goes to landfills.

• Making bioplastics often creates fewer greenhouse gases than regular plastics.

But there are some problems too:

• Crops for bioplastics can take space from food crops.

• Some bioplastics are hard to recycle, which makes trash harder to handle.

Material Efficiency in Packaging

Thermoforming helps you use less material for each package. This saves resources and makes less trash. You can pick new materials and ways to make things better:

• Recycled plastics from old products mean less new plastic is needed.

• Bioplastics like PLA can be composted after short use.

• Recyclable plastics like PET and HDPE can be made into new sheets.

You can make packaging work better by:

• Using one kind of material for the whole package, which helps recycling.

• Making walls thinner so you use less material.

• Adding clear labels so people know how to recycle.

New thermoforming methods let you make PET packages that can be recycled fully. Slit-and-fold technology uses just one material, so you do not need to pull parts apart for recycling. Closed-loop systems let you collect and reuse scrap from making packages. This keeps trash out of landfills and helps your business.

Tip: If you design packaging for recycling, you help your company and the earth.

You are important in making packaging better for nature. By picking good materials and smart ways to make things, you help the planet and follow new packaging rules.

Energy Efficiency and Process Innovation

Reducing Environmental Impact

You can help the environment by saving energy in your thermoforming plant. Many companies now use better heating parts in their ovens. These parts give steady heat but use less power. Control systems help keep the heat just right, so you do not waste energy. LED lights use less power than old lights. Motors with special drives only use the power they need. New air systems also help save more energy.

When you use these steps, you help the earth in many ways. You use less energy, so fewer greenhouse gases go into the air. You make less waste by recycling more. You also use less fuel to move packaging.

Some companies, like SAY Plastics, recycle almost all their materials. They use new plastic granulator machines to do this. This also means they need less packaging and less fuel for shipping. AI tools can help you lower your impact on the earth by up to 40%. You can do this and still make a lot of products.

Advances in Thermoforming Technology

New machines and tools help you reach your green goals. The table below shows how new upgrades help the earth and support recycling:

Other new things include robots and machines that work by themselves. These make work faster and cost less. Digital twins and AI help you find problems fast and make less waste. These tools help you recycle and use fewer materials. Faster machines mean you can make more packages with less harm to the earth. When you use these new ideas, you help protect nature and follow new rules for plastics and recycling.

Design for Recycling and Plastics Recycling

Recyclable Packaging Design

You can help recycling by changing how you design packaging. Many companies now pick PET for thermoforming. PET is accepted in most recycling programs. This helps the environment when you use it. More companies use monomaterial structures for food and medical packaging. Using just one material makes recycling easier.

• Over 60% of people in the U.S. can recycle PET packaging.

• Monomaterial packaging is used more in many industries.

• PET bottles are recycled more than PET packaging, but new projects want to recycle all PET items more.

You should also think about single-stream recycling. This system lets people put all recyclables in one bin. It makes recycling easier for everyone, but there can be problems. The table below shows how single-stream and dual-stream recycling are different:

When you design packaging for single-stream recycling, you help more people recycle. But you also need to make sure your packaging does not cause too much contamination.

Compliance with Plastic Bans

You have to follow new rules about plastics recycling and packaging. Many places now ban some plastics, so you need to change how you make packaging. Companies use different ways to keep up with these rules. The table below shows some ways you can adapt:

You can help your company and the earth by using these ideas. When you design packaging for recycling, you make it easier for people to recycle. You also follow new laws and help reduce waste.

Closed-Loop Systems and Sustainability

Integrating Recycled Content

You can help the earth by using more recycled materials. Many companies now add recycled content to their products. In 2023, PET thermoforms used about 17% recycled plastic. This was more than the 11% used in 2022. You often see recycled PET, PP, and HDPE in these items.

• Using recycled materials means you need less new plastic.

• You help recycling by giving old plastics new uses.

• You help cut down on waste and save resources.

There are some problems when you use recycled content. You must make sure your products stay safe and strong. This is very important for things like paint packaging that hold liquids. You also need a steady supply of good recycled plastics. Many companies work with suppliers to get the right materials.

Circular Economy in Thermoforming

A circular economy means you use materials again and again. You design packaging so it can be recycled into new things. Closed-loop systems help you collect and reuse scrap from your factory. This keeps waste out of landfills and helps the planet.

But there are some limits with thermoforming. The process works best with simple shapes. It does not work well with complex designs or undercuts. The table below shows some main limits:

You may also have problems when different plastics mix together. For example, closures made of HDPE and PP can make it hard to recycle PET bottles. This lowers the quality of recycled bales and makes closed-loop systems harder to use. Polyolefin closures often cannot be used again for food packaging, even after recycling. New mono-material PET closures help fix this problem. They make recycling easier and help a circular economy.

Tip: Pick simple designs and use one kind of plastic. This makes recycling easier and helps the planet.

You are important in making recycling work. By picking the right materials and designs, you help make packaging better for the earth.
