Blow molding
At Shell Polymers, we help plastic converters accelerate production, reduce downtime and bring new blow molded products to market with confidence. Our resins are engineered to help ensure consistency in wall thickness, aesthetics, and processability whether you're producing plastic bottles, soft drink containers, or industrial packaging applications. When working with us, you’ll Shell gain access to industrial-grade blow molding machines, designed to simulate real production conditions. This enables collaborative testing, faster resin qualification, and expert support—without interrupting your own manufacturing lines.
Expert insights on blow molding & market trends
Reduce blow molding defects with our processing conditions guide
Processing conditions are a key factor in the quality of a final, blow-molded product. Our team of blow molding experts have put together a guide to help reduce production errors, reduce defects and improve final product quality.
High-quality resin can increase blow molding machine production
Improving production is always a top priority for converters and resin plays an important role in this. Learn how suppliers can help ensure resin meets a converter’s quality needs.
Why the blow molded plastics market prefers HDPE
HDPE is incredibly versatile compared to other plastics and converters can use it to create an immensely diverse array of blow molding products across multiple applications.

Product 101
Understanding how we name our grade slates is key to choosing the right melt index and plastic resin density you need. Explore our naming convention below to know exactly what to look for when reviewing product detail for your next injection molded part or production run.
Density is reflected by the first two numbers found in the product name, which is 18 in this instance. These numbers represent the last two significant digits of the density value. See examples below.
18 = 0.918 density
53 = 0.953 density
63 = 0.963 density
