Adding Power to the Plastics You Already Use

The plastics supply chain supports most manufacturing sectors. These large manufacturers have utilized plastic as a raw material because, over previous decades, there have been reliable supply chains and low pricing.

But, today, that’s all changing. Prices are shooting up and people want to be more sustainable. This is causing companies to look for alternatives to further differentiate from the competition. Industrial hemp will help plastic compounders exceed client sustainability goals by making the plastics they already use stronger, lighter, cheaper, and more sustainable.

Global Transition

Although plastics are derived from petroleum, it’s no secret that the industry is moving toward a more sustainable future. The era of toxic fillers and reinforcement agents is coming to an end. This is the perfect opportunity for sustainable additives to make a positive impact.

The manufacturing companies that rely on plastic as a raw material have the opportunity to lead the transition toward sustainable products. Unfortunately, many of the leaders in manufacturing have hit the same roadblocks: strength, cost, and supply.

A Sustainable Competitive Advantage

Over the coming years, manufacturers that utilize plastic will try bio-based materials like industrial hemp to start transitioning their supply chain toward customers’ demands for more sustainable end products.

The only way manufacturers can leverage bio-based materials is if they have a reliable supply chain that can be consistently embedded into the various products they’re already selling. Bio continuity for industrial hemp comes down to material size, moisture, and surface area.

Sustainability Matters

The customers, employees, investors, and surrounding communities are all expecting leaders across industries to make decisions that put sustainability at the forefront of a companies vision and culture.

Now that hemp-based materials have hit price parity with toxic additives like talc, calcium carbonate, and fiberglass, manufacturers that utilize plastics can embed hemp into their raw materials supply chain without increasing their cost of goods sold (COGS).

Plastics That Leverage Hemp-Based Materials As Additives Are Stronger, Lighter, Cheaper, And More Sustainable Than Competing Products.

The Base Of The Plastics Supply Chain

For over 100 years, plastic has been the magical raw material that has reduced the weight and cost of most manufactured products. Unfortunately, prices are quickly rising which is leaving manufacturers searching for solutions that can reduce the end product cost while extending their plastic supply.

At the base of the plastics supply chain are plastics compounders. These compounders use virgin plastic and recycled plastic as base materials. Plastic compounders do all the heavy lifting by mixing in hemp fillers and other additives to ensure end-product manufacturers receive resin that matches their specifications. 

Once plastic and hemp are compounded into a masterbatch, the compounded product is then formatted into 3 types of raw input materials.


Sheets of plastic are typically used for products that require high strength and durability over decades.


Tubes of plastic are typically used for products that are being extruded in a continuous format.


Pellets of plastic are typically used for products that are made using 3D printers and various types of molding equipment.

Plastic Then Gets Distributed Across The World To Different End Product Manufacturers Across Industries.

End Product Manufacturing

As a Manufacturing company, adopting hemp filled plastic across your entire supply chain is as simple as asking your resin supplier for the same resin filled with hemp. It is that simple, your operating processes will remain almost identical to how it is today. In many cases, the working environment will be much safer.

Industrial hemp fillers work with any manufacturing process and most plastic types.


Injection, blow, compression, and roto molding techniques all work with hemp filled resin. We simplified the adoption process for plastics manufacturers by engineering fibers for your equipment.


Thermoforming and Vacuum Forming with sheet plastic is no different with hemp additives than it is with todays resins. Hemp is safer than glass and talc, while costing less and creating lighter end products.


Hemp filled resin has similar or higher flow rates than traditional resin while providing better end product characteristics. Hemp is also softer than mineral fillers, reducing equipment wear and tear.

It’s this simple: Ask your distributor or compounder about hemp filled resin, then call Heartland.

These Plastics Then Get Distributed To End Consumers.

Hemp Mixes With Common Plastics

Hemp-based additives can be used to enhance existing plastics that are already used across the world. We have focused on engineering our industrial hemp products to focus on creating bio continuity, so every pound of our product has the same size, surface area, and moisture content.

Manufacturers across industry sectors can utilize hemp-based materials as additives to strengthen the plastic they are already utilizing. These are just a few of the polymers that we have already mixed with.


Hemp fibers reduce the weight of a polyethylene & PET, while increasing metrics like tensile strength, elastic modulus, flexural strength, and flexural modulus.


Hemp fibers mixed with polypropylene have improved mechanical properties, low abrasiveness, superior energy recovery, good damping, and a high strength to weight ratio.

Polyvinyl Chloride

PVC is used in a wide range of structural material across the world. Hemp is a reinforcing material for PVC that will increase the stiffness while decreasing the density of the composite.


ABS (or Acrylonitrile Butadiene Styrene) can utilize hemp to strengthen the injection molding and 3D printing of plastics. Increased mold strength streamlines production.


Although bio-based PLA's are a long way away, hemp fibers as an additive to other polyesters has shown to increase overall strength and durability without jeopardizing weight and cost.


Vinylester mixed with hemp showed flame retardant properties of composites as indicated by the burning tests, thermogravimetry analyzes, and limiting oxygen index tests.

Hemp-Based Materials Mixed With Plastics Make A Biocomposite That Creates A Sustainable Competitive Advantage For Companies That Consistently Utilize Plastics.

Manufacturers Across Industries Need Stronger, Lighter, Cheaper, And More Sustainable Plastics.

Benefits of Carbon-Negative Additives On The Global Plastics Supply Chain

Plastics will never go away, so at Heartland we are focused on utilizing hemp-based materials as additives to enhance the plastics that companies are already using. By utilizing hemp materials, manufacturers are leveraging a bio-based filler that has a lower price than the additives they already work with.

Adding hemp-based materials to plastic can help companies evangelize a new generation of eco-friendly consumers and employees. Here are just a few of the benefits plastics companies experience by utilizing industrial hemp as an additive in their supply chain.

Lower Cost

Hemp fillers require less plastic to make the same product, ultimately reducing the end product cost for the first time.

More Strength

Hemp fibers are one of the strongest natural fibers on earth. Products filled with hemp have improved strength.

Lighter Weight

Hemp as a filler to existing products reduces the total weight. Lighter materials means lower logistics costs.


Hemp materials added to existing plastic products help companies exceed corporate sustainability mandates.

Plastics That Are Compounded With Industrial Hemp Are The Future of Materials That Make Markets Move.
