What do you want made from Hemp Plastic?
What do you want made from Hemp Plastic? This section is for you. We know you want products made from Hemp Plastic, but we cannot make everything at once. What do you think should be produced from this bioplastic first, and why? This section is monitored by our CEO, Paul Benhaim who will comment as he can.
Over 200 billion pounds (100 million tons) of plastics are produced each year.
45% of all plastics are produced in the United States.
29% of plastics produced in the US are used for packaging (15% building, 14% consumer)
Methods of Production FAQ
Injection moulding - the process of forming a material by forcing it, in a fluid state and under pressure, into the cavity of a closed mold. This is the most common production method used with Hemp Plastics.
Extrusion - a process in which heated or unheated plastic is forced through a shaping orifice (a die) in one continuously formed shape, as in film, sheet, rod or tubing
Compression moulding - the method of moulding a material already in a confined cavity by applying pressure and usually heat
Additives often used in plastic
Most polymers require chemical additives to make them of practical value. The additives industry is worth over $16billion/ annum.
Some of the types of additives are:
- Process Additives - lubricants, mold-release agents, and blowing agents
- Stabilizers - heat stabilizers, UV and visible light stabilizers, antioxidants, antimicrobial agents (preservatives)
- Plasticizer - a softening agent that is added to a polymer to facilitate processing or enhance physical properties. PVC (Polyvinyl chloride), for example uses 55% by weight of plasticizers. DINP (Diisononyl phthalate) is used as the softening agent in many pliable PVC toys.
- These plastic additives may potentially leach out of the plastics and cause environmental concerns. The effects of DINP in toys or DEHP in medical tubing/ products are a concern to the public.
- Compounding- the mixing of polymers with additives.
Plastic Identification Code Numbers and Meanings
Seven groups of plastic polymers, each with specific properties, are used worldwide for packaging applications (see table below). Each group of plastic polymer can be identified by its Plastic Identification code - usually a number or a letter abbreviation. For instance, Low-Density Polyethylene can be identified by the number 4 and/or the letters "LDPE". The PIC appears inside a three-chasing arrow recycling symbol. The symbol is used to indicate whether the plastic can be recycled into new products.
The PIC was introduced by the Society of the Plastics Industry, Inc. which provides a uniform system for the identification of different polymer types and helps recycling companies to separate different plastics for reprocessing. Manufacturers of plastic products are required to use PIC labels in some countries/regions and can voluntarily mark their products with the PIC where there are no requirements. Consumers can identify the plastic types based on the codes usually found at the base or at the side of the plastic products, including food/chemical packaging and containers. The PIC is usually not present on packaging films, as it is not practical to collect and recycle most of this type of waste.
- 1 - Polyethylene terephthalate (PET, PETE)
- 2 - High-density polyethylene (HDPE)
- 3 - Polyvinyl chloride (PVC)
- 4 - Low-density polyethylene (LDPE)
- 5 - Polypropylene (PP)

weight: PP has a specific gravity of 0.9 whereas natural fibres have a specific gravity of 1.3. So the more fibre is added, the 'heavier' the compound becomes. Our most popular compounds have densities roughly between 1.0 and 1.1

MOQs (Minimum Order Quantities)
- Materials - As a material supplier and cannot supply less than 1 ton as a very minimum first order. Prices decrease for larger amounts.
- Products - Generally manufacturing of a product is not worthwhile for anything less than 50,000 pieces. There is always a start-up cost involved that is often significant.
- Please visit the current materials or oem manufacture page for further information.

Recycled, Biodegradable, Compostable and Virgin materials
Our core materials, although up to 80% hemp fibre bio based is recyclable. We are able to manufacture a PLA & plant fibre blend that is biodegradable or compostable depending on your specific requirements. We have produced specific compounds for major multinational OEM's within the electronics industry (sorry, they have not given us permission to talk about this in writing yet) for items we hope they will commercialize in the near future. We can do this for you as well, though there are costs involved in R&D so quantities need to be appropriate for this work.
We are promoting two main materials as they are the most cost effective and technical stable and strong materials we have found. We believe that by substituting around 50% of the PP for plant fibres is more than enough to call the material environmentally sustainable as it ensures product stability and longevity suitable for a wide range of applications. Please read more at our current materials page or request a sample today.
In the 1910s Henry Ford experimented with using agricultural materials in the manufacture of automobiles. Ford was partly motivated by a desire to find nonfood applications for agricultural surpluses, which existed then as they do now. He tried out many agricultural crops, including wheat.
Why Hemp Plastic?
We are suppliers of high quality bulk hemp based bioplastic materials for a green and sustainable future. Affordable and biodegradable material solutions for a consuming planet of green consumers. A great alternative to polypropylene injection moulding and glass-reinfored fibre plastics that requires no change in your production equipment.
If today is a typical day on planet Earth, we will lose 116 square miles of rainforest, or about an acre a second. We will lose another 72 square miles to encroaching deserts, as a result of human mismanagement and overpopulation. We will lose 40 to 100 species, and no one knows whether the number is 40 or 100. Today the human population will increase by 250,000. Tonight the Earth will be a little hotter, it's waters more acidic, and the fabric of life more threadbare. Today oil is becoming more scarse and our carbon footprint is far too high. Hemp is a better quality and sometimes more affordable substitute for petrochemical plastics.
“The world doesn’t need another plastic DVD case, CD case or any other plastic case. The millions manufactured, sold and dumped daily is a horror story. How they are manufactured and by what process is yet another horror story. It’s all to do with the fact that they are made by petro-chemicals. Petro-chemicals are a finite resource. As well as a source for our fuel they are the foundation for many of the items we find around us every day. Our computers, mobile phones, body-care containers, water bottles, furniture and even clothing. The use of these products are increasing. This cannot continue sustainably without further global warming. Hemp is a great alternative bioplastic.“ Dame Anita Roddick, Founder of The Body Shop PLC
