Plastic trays are an important facet to a number of industries and are rapidly replacing metal trays.

2. Improving on existing products and systems to improve output,
efficiency and effectiveness is at the core of innovation. It’s about
working smarter not harder. Innovation is the absolute key to the
growth of the mining and minerals industries. These industries rely
heavily on continuous innovation to drive growth.
And with regards to that, it is the innovation that has led to the
implementation of plastic trays in these industries with a motive of
making the process simpler. Plastic trays have a number of benefits
with accordance to the materials that have to be stored or presented
in these trays. There are certain minerals that react to a metal tray in
a vague manner, but are well summoned on a plastic one.

3. Here are some key benefits of plastic trays in the industries:
Convenience
They have ergonomically designed built-in handles so that they are
easier to pick up and handle, coloured coded for easy recognition
and are also available in black. These trays are designed to stack well
on pallets and aren’t noisy like metal core trays, they are planted
with effective drainage holes ensuring that core samples are not
damaged or contaminated. They can be easily labelled with a
permanent marker or paint pen or an optional aluminium tag that
holds onto the ID tag holder.
Productivity
Metal core trays are hard to pick up, especially when hot! Are
difficult to handle and when damaged, need to be replaced which
means a loss in productivity. Improved plastic core tray designs
means that they are easier to use and stack easily for storage and
transportation saving time and resources - thereby enhancing
productivity. Certain models in these trays can even nest effectively
halving transport costs when the tray is empty.
Longevity
Metal core trays have a tendency to rust and have a shorter life span
as a result. Plastic core trays are made of premium UV stabilised

4. polypropylene, a type of thermoplastic polymer resin that can be
found in many goods such as loudspeakers, automotive components
and carpets. This chemical compound is not only highly resistant to
organic chemicals (to minimise risk of a chemical reaction with core
samples) and is non-magnetic (so as not to interfere with core
analysis) but will not corrode like metal core trays. These types of
plastic trays are generally so durable, that they are assumed to last
for about an approximate time of 20 years.
Cost-effectiveness
The components of metal core trays are normally higher in costs
which make them more expensive to manufacture. These costs are
subsequently passed down to the customer. In comparison, plastic
core trays are cheaper to produce and so are cheaper than metal
core trays. And as they are also more durable, plastic core trays
represent good value.
Safety
Metal core trays have sharp edges making it difficult to pick them
without inflicting cuts to hands. Sharp corners can also catch on
clothing. When left out in the sun for great lengths of time, metal
core trays can also become hot to touch and burn the skin, making it
difficult to pick up and handle without the use of safety gloves.
Plastic core trays eliminate these safety issues because they have
rounded edges and are cool to touch even when left for long periods
of time in the hot sun. Because there is less risk of injuries and other
OHS issues, plastic core trays are a much safer option.

5. Plastic trays are an important facet to a number of industries and are
rapidly replacing the metal trays. The reason for this to happen is
indeed quite obvious after the number of key benefits mentioned
above; there is a clear sight as to why plastic trays are the more
preferred version of trays.
