HDPE Blow Molded Plastic Recycling

High-Density Polyethylene (HDPE) is a workhorse material in the industrial world. From bottles and containers to blow molded parts and runners, it’s widely used due to its strength, chemical resistance, and recyclability. For manufacturers and distributors, HDPE blow molded scrap is a valuable resource—and Seraphim Plastics helps you transform that scrap into profit.

As a commercial-only plastic recycler, Seraphim Plastics specializes in post-industrial plastic recycling, including blow molded HDPE materials. If your facility produces HDPE waste from packaging, manufacturing, or processing operations, we want to buy it.

In this article, you’ll learn exactly which types of HDPE blow molded materials we accept, how to prepare your scrap for pickup, and why Seraphim Plastics is the trusted name in industrial plastic recycling across the Midwest and Southeast.

What Is Blow Molded HDPE?

Blow molding is a manufacturing process used to form hollow plastic parts by inflating a heated plastic tube inside a mold. HDPE is one of the most common resins used for blow molding due to its lightweight strength, impact resistance, and versatility.

Key Characteristics of Blow Molded HDPE:

  • Hollow interior (bottles, drums, tanks)
  • Strong walls and chemical resistance
  • Lightweight yet rigid
  • Commonly found in packaging and industrial use

Seraphim Plastics accepts various HDPE blow molded scrap forms, as long as the material is clean, single-resin, and generated in a post-industrial setting.

HDPE Blow Molded Materials We Accept

Here’s a breakdown of the types of HDPE blow molded scrap that Seraphim Plastics purchases and processes.

1. HDPE Bottles (Baled)

We accept baled post-industrial HDPE bottles, such as:

  • Blow molded detergent bottles
  • Motor oil containers
  • Chemical bottles
  • Personal care product bottles

These are typically generated in high volumes by:

  • Packaging plants
  • Product filling facilities
  • Industrial bottle manufacturers

Requirements:

  • Bottles must be post-industrial only (no post-consumer recyclables)
  • Color-sorted bales (natural, white, mixed color, etc.)
  • No contamination with paper labels, foil, or caps
  • Bales must be tight, uniform, and properly bound

Baled HDPE bottles are a valuable feedstock for regrind and pellet production.

2. Blow Molded HDPE Parts

We purchase HDPE blow molded parts that are clean and uniform in resin type. These often include:

  • Tank components
  • Hollow industrial containers
  • Air ducts or fluid reservoirs
  • Automotive parts
  • Storage containers or jugs

These parts often come from:

  • Blow molding manufacturing facilities
  • Packaging component suppliers
  • Custom molders producing OEM parts

Accepted Scrap Sources:

  • Discontinued or obsolete parts
  • Rejected production parts
  • Broken or damaged inventory

All materials must be free from contamination, including metal fasteners, rubber inserts, or multi-resin blends.

3. Spurs and Runners

In blow molding, spurs and runners are excess plastic formed during the mold filling process. These are ideal for recycling into regrind.

We accept:

  • Solid spurs and runners trimmed off from blow molded items
  • Clean, uniform HDPE waste with no mixed resins
  • Bagged, boxed, or loaded in gaylords

These are typically byproducts from high-volume production lines and represent a consistent source of scrap.

4. HDPE Purge

Purge refers to hardened lumps or chunks of plastic purged from blow molding machines during maintenance, resin changes, or color transitions.

At Seraphim Plastics, we accept:

  • HDPE purge chunks
  • Cold machine purge slabs
  • Mixed-color purge (HDPE only)

Requirements:

  • Must be 100% HDPE with no cross-contamination
  • No embedded metal
  • No post-consumer additives or coatings

Purge is a valuable material in recycling streams when clean, as it can be ground down and used in new blow molding applications.

5. HDPE Regrind

Regrind is HDPE plastic that has already been processed into flakes or ground material. It is ready for reintroduction into the manufacturing process.

Accepted HDPE regrind must be:

  • Produced from blow molded HDPE (not injection molded)
  • Consistent in size (3/8” or smaller is ideal)
  • Free from labels, dirt, or foreign materials
  • Sorted by color and grade (natural, white, black, etc.)

Packaging:

  • Super sacks, boxes, or gaylords
  • Clearly labeled by resin type and source

We work with manufacturers who grind their scrap in-house and are looking for a trusted partner to purchase regrind in bulk.

6. HDPE Pellets

Seraphim Plastics also buys HDPE pellets—both virgin and recycled—for reuse in manufacturing operations. These often come from:

  • Plastic resin producers
  • Manufacturers with excess or off-spec runs
  • Distributors offloading surplus stock

Accepted Pellet Types:

  • Virgin HDPE pellets
  • Recycled HDPE pellets from blow molded products
  • Off-color, off-spec virgin pellets

Pellet Packaging Guidelines:

  • Bagged in 25-50 lb bags
  • Super sacks or boxed
  • Clearly marked for identification

This material is ready to re-enter the production cycle, making it a highly desirable commodity.

7. Virgin Off-Spec HDPE

We accept off-spec virgin HDPE from resin producers or processors. This includes:

  • Pellets with color inconsistencies
  • Slightly off melt index
  • Pellets that didn’t meet original QC specs

Note: Off-spec doesn’t mean unusable—many manufacturers use off-spec resin in non-critical or secondary product lines.

We help you find a second life for this high-value resin, keeping it out of the landfill and putting it back into circulation.

Preparing Your HDPE Blow Molded Scrap for Recycling

To ensure a fast and profitable transaction, follow these preparation tips:

✅ Separate by Type

Keep HDPE blow molded scrap separate from other materials like injection molded HDPE, polypropylene (PP), or PET.

✅ Remove Contamination

No dirt, adhesives, foil seals, caps, or metal attachments. Clean, single-resin material is essential for quality recycling.

✅ Package Properly

  • Baled bottles: tightly compressed, banded
  • Parts, purge, runners: boxed or loaded in gaylords
  • Regrind and pellets: super sacks or clearly labeled containers

✅ Label Clearly

Include details like:

  • Resin type (HDPE)
  • Form (bottle, part, purge, regrind, pellet)
  • Color
  • Origin (if known)

This speeds up inspection, processing, and payment.
