UNIPAK Baling twines, or baler twine is a skinny diameter synthetic, or sisal twined nylon rope used widely in the craftsmanship industry for all kinds of binding, tying and looping applications. Baler twines are usually made of synthetic fibres resulting from cross-bond processes using polyester or nylon. This type of threading can be woven in a variety of decorative patterns, producing a wide array of artistic products. The use of this thread in the making of baler twine can result in a wide variety of artistic bindings such as booklets, notepads, brochures and promotional materials.
Baling threading can be described as joining two fibre strands with a filler that causes the fibre to expand in a controlled manner producing a strong bond. Cross-linked tensile fibres are the most common materials used in baler twine. Baling threading is a high tensile strength fibre due to the tensile strength of the individual threads. Tension is applied to personal lines through mechanical tension force applied through hinges and pinions. The threads work as a unit when a greater amount of tensile strength is used, resulting in a stronger bond generation.
A bale is a unit of measurement that is either a horizontal or vertical dimension measured by length and thickness. The material used in UNIPAK baler twine binds consists of both a central core and outer cover layer of yarns, silk, cotton, polyester, nylon, acrylic or polypropylene fibres. The core is often made of a thick polyester sheet material while the outer cover is typically made of a thick cotton or polyester material.
Cross-linked yarns are used in baler machines because of their high tensile strength and fine threading. They are woven together in a way that enables them to adhere closely to each other. Natural fibres such as wool and cotton can also be used, but because these fibres are soft and do not have cross-linking properties, they cannot withstand the extreme pressure applied to them. Also, cotton is susceptible to puncturing, while wool fibres are stain-resistant. These properties make bales ideal for use with baler twine binders.
Although bales are commonly made from natural fibres, other materials are also used. For instance, Silk may be included in some bales but it is more commonly used for manufacturing other items such as bedspreads and tablecloths. Polypropylene was once used in baler twine but is now considered a low-quality fibre. However, some companies still produce balers using polypropylene fibres, although they are far from being as strong as natural fibres.
When using UNIPAK baler twine in binding, there are a variety of different binding methods available. One must understand how each method works to make the right choice for the specific project at hand. The most common method is the standard mechanical binding where the edges of the bale are stitched together, and the middle is wrapped around the sides. Other binding methods include hot lamination and adhesive glue down. A popular synthetic twining method is called cross-twinning and has been successfully used for many years.
