Abstract
An elastic wrapper netting, and a method for making same, wherein linear low density polyethylene ribbons are knitted into a Raschel net. The ribbons of the knitted wrapper netting have an orientation of about 1:4.25 in the longitudinal direction.
Claims7
A knitted thermoplastic netting comprising longitudinal ribbons and lateral ribbons wherein:
- the ribbons consist essentially of linear low density polyethylene, said ribbons being oriented and having a ratio of stretched oriented length to original substantially unoriented length of between 1:4 to 1:5;
- and
- the longitudinal ribbons have an elastic limit of more than about 6%, an elongation at break of more than about 60%, and a elasticity of more than about 15% when stretched more than 40%.
A knitted netting comprising longitudinal and lateral ribbons, said ribbons having been cut from a substantially unoriented primary film consisting essentially of linear low density polyethylene, wherein said ribbons, are oriented and have a ratio of stretched oriented length to original substantially unoriented length of between 1:4 to 1:5,
- said longitudinal ribbons having a width of between about 1.2 mm and 1.3 mm, and a thickness of between about 0.04 mm and 0.05 mm.
- said lateral ribbons have a width of between about 1.2 mm and 1.3 mm and a thickness of between about 0.02 mm and 0.03 mm;
- the longitudinal ribbons have a denier of between about 430 and 460, and the lateral ribbons have a denier of between about 240 and 250;
- and
- the netting having an elastic limit of at least about 6%, an elongation to break of at least 60%, and a elasticity of at least about 15% when stretched more than 40%.
A wrapped bale of agricultural crops, comprising:
- a cylindrical body of agricultural crops;
- and
- a knitted thermoplastic netting comprising longitudinal and lateral ribbons, said ribbons consisting essentially of linear low density polyethylene, said ribbon being oriented and having a ratio of stretched oriented length to original substantially unoriented length of between 1:4 to 1:5;
- and said longitudinal ribbons having an elastic limit of more than about 6%, an elongation at break of more than about 60%, and an elasticity of more than about 15% when stretched more than 40%.
- wherein said knitted netting extends about the circumference of said cylindrical body enclosing and maintaining the crops therein.
