Repulpable paper strap with enhanced moisture resistance and methods to make the same

A method of forming a repulpable paper strap, the method comprising:

• providing a plurality of paper strings;
• directing the paper strings through one or more pultrusion dies;
• and
• injecting a binder to bond the paper strings, the binder including a dicarboxylic acid, a partially hydrolyzed polyvinyl alcohol, and a fully hydrolyzed polyvinyl alcohol;
• wherein the binder, by dry weight, approximately includes the partially hydrolyzed polyvinyl alcohol between 30 to 70 percent.

A repulpable paper strap comprising:

• a plurality of paper strings;
• and
• a binder that binds the paper strings together, the binder including a partially hydrolyzed polyvinyl alcohol and a fully hydrolyzed polyvinyl alcohol;
• wherein the binder further comprises a dicarboxylic acid and, by dry weight, approximately includes the partially hydrolyzed polyvinyl alcohol between 30 to 70 percent.

A repulpable paper strap comprising:

• a plurality of paper strings;
• and
• a binder that binds the paper strings together, the binder including a partially hydrolyzed polyvinyl alcohol and a fully hydrolyzed polyvinyl alcohol;
• wherein the binder, by dry weight, approximately includes a dicarboxylic acid between 35 to 40 percent.

A repulpable paper strap comprising:

• a plurality of paper strings;
• and
• a binder that binds the paper strings together, the binder including a partially hydrolyzed polyvinyl alcohol and a fully hydrolyzed polyvinyl alcohol;
• wherein the binder, by dry weight, includes the partially hydrolyzed polyvinyl alcohol between 38 to 40 percent, the fully hydrolyzed polyvinyl alcohol between 20 to 22 percent, and a dicarboxylic acid between 38 to 40 percent.

A repulpable paper strap comprising:

• a plurality of paper strings;
• and
• a binder that binds the paper strings together, the binder including a partially hydrolyzed polyvinyl alcohol and a fully hydrolyzed polyvinyl alcohol;
• wherein the strap, when exposed to an environment of between 85 to 90 percent relative humidity and between 35 to 40 degrees Celsius, does not lose more than approximately 2 to 5 percent tensile strength of the repulpable paper strap.
