This favoured packaging solution has many uses worldwide. It is stronger than regular paper and creates a perfect source of packaging that is used in everyone’s daily life. The packaging is usually multi-ply, meaning it has several layers that make it stronger. It comes in different strengths, colours and textures for different uses. The industry grew when produce started to be sold in bulk, instead of single items locally. There needed to be an alternative to the packaging process to keep produce and products safe or fresh. This humble creation allows humanity to successfully trade in bulk locally and globally.
Deriving from the wood of trees the packaging is made from different pulp solutions. There are three main fibres that are used in combination in different ways to create different strengths. There are two different fibres; long and short. Spruce and pine wood both have long fibres and birch has short fibres. These fibres are blended in different ways and combinations to achieve the properties desired for specific purposes. The wood used is grown in sustainable forests or made of recycled materials. As the demand increases, more factories are needed for higher productions. Generally, all of the processes happen in the same factory such as the pulp production and the mills.
Why Is Cardboard Different?
Paperboard has a more complicated manufacturing process. It will go through several processes to create the required look and feel. The packaging can be bleached, coated and has variations of recycled packaging. Polyethylene resin is sometimes needed to be able to contain liquid food products, such as milk. The cardboard process does not include any polyethylene resin. Cardboard manufacturing is much simpler because it generally does not need a colouring process involved. Cardboard is generally heavier too as it is designed to be more heavy-duty.
What Is Coating Used For?
Coating and lamination can be used to make the packaging better for certain uses. The packaging is coated with plastics which have protective and sealing properties. The packaging’s properties combined with the relatively small amounts of plastic materials, can provide the extra features needed for several specific demanding applications.
Extrusion coating is the application of molten plastic to the packaging. It is then chilled to form an extremely thin, smooth layer. The molten plastic can be used as an adhesive to laminate a plastic film or a metal foil.
Both lamination and extrusion coating are used to achieve certain things. This can be things like: moisture protection, grease resistance, sales appeal or heat sealing. These properties are highly sought in particular industries like the food industry.
Yes, it can be recycled. It is a very eco-friendly process as far as packaging goes. The wood used to make the pulps are grown in sustainable areas of forest. This means that there are as many trees being planted as there are being chopped down. Therefore, the supply and demand will always be met without having to chop down more areas of unprotected forests. This is important because too many animals are being pushed onto the endangered species list from lack of habitats, and more contact with human activity. It is widely recycled worldwide. The only issue is that it can be harder for the manufacturer to determine the concentration of different fibres that are going to be in the recycled waste. The recycled packaging will be used for its own purposes where it can guarantee to be efficient. Due to the need for a more eco-friendly approach to packaging, recycling has been increased and more companies want to use recycled packaging. The only global problem is when people do not recycle their packaging and it ends up in landfill sites. Generally, it does disintegrate much quicker than other packaging in landfill, it just takes up more space. The resulting compost is not as bad for the surrounding environment as plastics either.
Paperboard is generally thicker and stronger than paper. Paper can be used in packaging but more as wrapping, internal bedding for products or labels. Paper goes through less manufacturing processes and is not used as the actual boxing or carton for products as it is not as stronger. Paper easily tears and is not suitable for wet substances.
There are many uses for packaging worldwide. The food, health and retail industries are huge users of paperboard. The food industry uses it for e.g. cereal packaging and juice cartons. The health industry uses it for medicine packaging and retail use it for product packaging. We encounter it on a daily basis from our toiletries to our cupboard foods, we all have it within our homes.
