There are different kinds of bulk bags available for a variety of purposes, with the main types being polypropylene bags and polyvinyl chloride bags, also known as PVC bulk bags.
Both types of bulk bag can hold large quantities of weight, and are often used for storing and transporting materials such as food products, grains and seeds. Both polypropylene and polyvinyl chloride bags are also frequently used to store and transport construction and landscaping aggregates such as sand, fibreglass and even chemicals.
Knowing whether PVC bulk bags or a polypropylene bulk bag is the best choice for your purposes is important as there are some key differences. Here we explain what each bulk bag material is and the differences between each of these bulk bag packaging materials.
Polypropylene Bulk Bag
Polypropylene is the ideal packaging material for builders bags, baffle bags and standard bulk bags. It’s a strong and durable material, with a bulk bag made from polypropylene able to withstand heavy materials and loads. These bags are also very versatile and can transport and store a wide range of materials.
It should be noted that while polypropylene is moisture resistant, it is not waterproof or watertight. It is cost effective though, and the polypropylene material has a long shelf life thanks to its robust durability.
This type of bulk bag is commonly used within the construction and general packaging industries.
PVC Bulk Bags (Polyvinyl Chloride Bags)
Polyvinyl chloride bags or PVC bulk bags as they are more commonly known, feature fully welded seams which serve the purpose of making the bag completely watertight to protect the contents inside. They are also very strong and durable, and the additional ability of PVC to withstand weathering and heavy loads makes the material popular for making watertight bags for the likes of fishing and other water bound activities.
A key difference between polypropylene and PVC bulk bags is that the latter polyvinyl chloride bags can be coated with a variety of special coatings. These coatings then enable the PVC bulk bags to be certified for use within the food or pharmaceutical industries. PVC bulk bags are also able to contain hazardous materials, so long as they are UN certified materials.
Ultimately, PVC bulk bags are stronger and completely watertight compared to polypropylene bags.
Additional Features Of Polypropylene And PVC Bulk Bags
The packaging materials used for both polypropylene and polyvinyl chloride bags can be recycled, thus making them a sustainable packaging product. Both materials can also be customised with a business logo, as well as being coloured to match the colour scheme of the business brand.
