30% RPET vs 50% vs 100% RPET: Which One Makes the Most Sense? Choosing RPET sheet isn't simply about buying the highest recycled content. For many packaging buyers, the better question is: Which RPET percentage best matches your product, budget, and sustainability goals? Here's a quick overview: ✅ 30% RPET Stable production Excellent transparency Cost-effective for large-volume projects ✅ 50% RPET The most balanced option Popular with retailers and food packaging brands Strong ESG performance without compromising process stability ✅ 100% RPET Maximum recycled content Ideal for brands promoting sustainability Supports circular economy initiatives and carbon reduction goals Another important point: RPET and GRS Certified RPET are not the same. GRS certification verifies recycled content through a traceable supply chain, helping procurement teams meet ESG reporting and customer compliance requirements. If you're sourcing thermoforming sheet for food packaging, understanding this difference can save time during supplier qualification.

PET sheet is widely used in thermoformed packaging, but medical packaging is a different conversation. A PET sheet that performs well in food trays, consumer blister packs, or standard retail packaging is not automatically the right choice for medical blister packaging or thermoformed device trays. In medical applications, the buying decision often goes beyond clarity and formability. Buyers may also need to think about formulation control, traceability, repeat consistency, and whether the supplier can support the project over the full qualification cycle. In this article, we take a practical look at why PET cannot always be used freely in medical packaging, and what medical packaging buyers should check before placing an order. We also compare APET, PETG, and GAG from a thermoforming perspective and discuss common sourcing mistakes that can create problems later in production. If you work with medical trays, blister packaging, or thermoformed PET sheet, this guide is written for the buying side of the project rather than the textbook side.

Cold temperatures change everything — especially for plastic materials. Not all sheets behave the same once you hit freezing conditions. PET vs PP is a common question in packaging, and the difference becomes pretty obvious in cold chain use: PET: ✔ stays tough ✔ handles impact ✔ keeps its shape PP: ✖ can get brittle ✖ more prone to cracking If you're working with frozen food packaging, this is worth a look.

PLA vs PET Sheet for Food Packaging: Which Material Makes More Business Sense? PLA is often promoted as the sustainable future of packaging. PET is sometimes viewed as the traditional option. But when packaging manufacturers evaluate materials, the decision usually involves much more than sustainability claims. Questions such as: How efficiently will it thermoform? What will the scrap rate be? Is the material widely recyclable? How stable is the supply chain? What is the total packaging cost? can have a greater impact on a project's success than the material's environmental marketing alone. In our latest article, we compare PLA and PET from the perspective of thermoforming performance, recyclability, cost, and real-world packaging applications. The results help explain why PET remains one of the most widely used materials in food packaging today. #FoodPackaging #PETSheet #PLA #Thermoforming #PackagingMaterials #RPET #Manufacturing #PackagingIndustry

New Article: Is Paper Really Replacing Plastic in Thermoforming? Paper packaging is growing rapidly, but plastic remains essential in many thermoforming applications due to its performance, recyclability, and product protection capabilities. Learn how packaging buyers compare paper, PET, rPET, PP, and molded fiber when selecting materials for food packaging and retail applications. Read more:

Most discussions about PET thermoforming defects focus on material quality. That's understandable—but it's not always accurate. When whitening appears on corners or cracks develop after molding, the immediate reaction is often: "The sheet must be bad." Yet some of the most persistent cases we've seen were caused by: • Low forming temperatures • Aggressive draw ratios • Poor plug-assist design • Sharp mold transitions PET is an excellent thermoforming material, but it tends to reveal process weaknesses more visibly than PP. The interesting part is that whitening itself is often just a symptom. The real challenge is identifying whether the stress originated from the material, the mold, or the process conditions. For production teams, the fastest path to a solution is usually a structured diagnosis rather than a supplier change. What do you check first when PET parts start whitening?

Extruded vs Calendered Plastic Sheets: Which Process Makes More Sense for Thermoforming?

When buyers compare plastic sheets, they often focus on material names first: PET, PP, PS, PVC, PETG. But experienced thermoforming factories know something more important: Sometimes the manufacturing process matters just as much as the resin itself. Two sheets may use similar raw materials, have similar thickness specifications, and even look almost identical in photos. Yet once they enter…
