UNIPAK Baler Twines and Baling Machines

Baler twines are an artificial thin, flexible sisal or synthetic textile material used as an adhesive to bind a relatively small fibrous material to a relatively large and easily measured package. Baler twines were created for the manufacturing industry, where they are extensively used in binding package forms such as suitcases, shipping boxes, books and magazines, to name a few. The strength of balsa twines is in their ability to adhere and their power to be reused multiple times. The number of woven fabric layers that make up a UNIPAK baler twine usually ranges from three to nine. However, other variations and customisation may also be incorporated into the design. Baling twines can also produce decorative trinkets and decorative items such as figurines, birdhouses and wind chimes.

 

Baling twines, and wire bindings came into prominence during World War II when the US military temporarily suspended troops’ movement during operations. Wire mesh was used as coverings over sleeping bags and rations to reduce the possibility of dust and riddance affecting the body’s temperature and comfort of the personnel. The friction between the synthetic twining wire and the air resulted in friction heat which caused the bags to lose perspective and become hard to sleep on. The bags were also not as breathable as one might expect due to the lack of air, making it difficult for the troops to perspire whilst working on campfires or under the hot sun. The British Armed Forces adopted wire mesh as a temporary wire binding material.

 

Baling bales are primarily manufactured from man-made fibreglass pellets harvested from various sources, mainly alfalfa, buckwheat and sisal fibres. Man-made materials are more resistant to temperature fluctuations than fibreglass but less dense than sisal fibres. They are available in both short and long lengths and come in various thicknesses, from the lightest bedding material to the largest to match a particular need. In addition to being adaptable, bales are customisable through the addition of individual sisal fibres. This makes it possible to utilise bales for any number of applications while keeping the visual appearance.

 

The primary material utilised in baling is polypropylene, also known as PP or polystyrene. It was first developed in the 1970s and is manufactured today with high-end engineering techniques. Polypropylene is most often mixed with an appropriate resin to increase its strength and durability. When combined with the aforementioned hay and water solution, the resulting product holds tightly together due to the inherent interlinking of the two materials.

 

Another option available is to purchase UNIPAK baler twine, which contains a combination of natural fibres. These bales are constructed by “threading” natural fibres together rather than layering them like PP. The resulting product is strong enough to withstand extremes of temperature and moisture but can also be made thinner to accommodate smaller areas with less weight.

 

A popular option for making straw bales is to utilise a combination of polypropylene and natural fibre materials. Many people use these balers because they are less expensive, provide versatility, and require less maintenance than most other balers. The construction of a UNIPAK baler twine consists of two layers of polypropylene fibres threaded together with a reinforcement layer in between. This reinforcement layer is most often steel, aluminium, or copper, providing a level of strength that rivals that of standard synthetic fibres.
