What Is A Presswood Pallet?

Presswood pallets, also known as molded wooden pallets, are made of wood byproducts such as waste pallets, raw wood shavings, wood waste, saw-dust and any other material containing wooden fibre.

Presswood pallets are moulded pallets made from waste wood. They are the ultimate recycled, and recyclable pallet. In fact, some of the most worn out wooden pallets that can no longer be repaired or reused are chipped to help create presswood pallets.

Their unique design means that they can hold substantial load capacities, whilst also being relatively lightweight. They are also both stackable and nestable, helping to reduce storage space and freight costs during shipment.

Generally they are made from ‘resinous’ trees (pine, fir, etc.), the chips come directly from logging and sawmills or from the wood recycling industry. This makes this particular type of pallet extremely eco-friendly.

How Are Presswood Pallets Made?

Compressed wooden pallets are manufactured in the same way as particle board. This manufacturing process involves mixing wood particles or flakes together with a resin before molding into sheets.

In order to separate the wooden chips into smaller pieces, they are first passed through a small hammer mill. Using a small sieve, they are then separated according to size.

The chips are then dried at temperatures as high as 65°C. This is to extract as much moisture as possible to a level of less than 10%.

Once dry, these chips can then be molded using a compression molding process using a similar binder to particle boards.

The pressure and temperatures involved can reach as high as 85kg/cm2 and 150°C, respectively.

This hot compression molding process is used to kill all living plant pests. The high density of this type of pallet, as high as 1.3 g/cm3, means it is resistant to all wood boring insects and infestations.

The molded presswood pallet machine provides an innovative presswood manufacturing process by recycling the materials mentioned above using high heat and pressure to create insect-free pallets. With this machine, the production of presswood pallets can divert millions of pounds of wood and plant fibers from landfills to productive use each year.

What materials can be used for the production of a presswood pallet?

There are a lot of wood waste in wood working factories, furniture factories and other sawmills. You can get raw materials very easy.

  • Waste wood, scrap of the wood, sawdust wood chips, wood shaving, wood chips, big chips, raw wood, burned forest, logs, wood board, branches, timber, wood flakes, waste furniture, and waste pallets, and so on.
  • Contenting rich fiber also can be used to produce the pallets, such as straw, waste kraft paper, bamboo, palm trees, coconut, softwood, cotton straw, wheat straw, corn straw, bagasse, and miscanthus, and so on.

What advantages do the presswood pallets outweigh the traditional solid wood pallets?

  • The presswood pallets are much lighter in weight and less expensive than the traditional solid wood pallets.
  • The presswood pallets are twice as stiff as new hardwood pallets so that they are more stable for improved product protection during transportation.
  • They perform greater resistance to fork-related, pallet edge damage compared to nailed pallet boards.
  • Since they are sanitized under high temperature and pressure during the molding process, there is no need for stamps and expensive heat treatments.
  • They are clean, free of listeria and other contaminants.
  • The bio-based presswood pallets typically price much less than hardwood pallets for using low-cost renewable, plant-based materials. Most importantly, they are 100% recyclable.
  • With a space-saving nestable design, light-weight molded presswood pallets are cost-effective alternatives to conventional heat-treated wood
