There are now several government regulations placed on the handling of food products in the agricultural and industrial sector. One of these regulations involves the type of material used for your food handling container. The ideal material option for food handling currently is plastic.
Large plastic bins can be vented to allow rapid cooling and minimise food spoilage, are stackable and easy to maintain and clean. Unlike the wooden bins used in the past, plastic containers have no nails, splinters, and risk of bacterial contamination.
Here are the processes used in manufacturing these plastic bins:
This process involves making a hollow length of plastic, which is then pre-shaped and closed in around a parison. Air pressure is then used to expand the parison which extends according to the mould’s shape. The interior part of the mould stays hollow. Blow-moulded containers have uniform thin walls.
In this option, manufacturers heat a closed mould in a furnace where it rotates as a plastic powder coats its interior. The heat liquefies the plastic used into a single layer which conforms to the mould cavity’s shape and leaves a hollow cavity.
Rotational moulding is ideally used for large plastic containers since it is slow. The containers thus created are cheap and eco-friendly since the process is economical and has minimal material waste.
In this process, manufacturers force melted plastic through a die shape with a rigid cross section. The die’s shape will determine the manufactured container’s final shape, and hence extrusion moulding can form a variety of configurations. It is however only used for thermoplastics.
These manufacturing processes for plastic containers are more costly than those used for other materials. The products created might be more expensive, but they are incredibly durable and more cost-efficient. Plastic containers will, therefore, be the best option for the food handling industry.
