Recycled white ticket stock and method of making same

Abstract

A ticket stock and manufacturing process wherein a pulp is formulated from a blend of recycled furnishes, with added starch for enhancing sheet stiffness and reducing linting and dusting on cut edges of the stock, and clay or other opacifier for enhancing opacity of the stock. A preferred pulp comprises a blend of recycled solid bleached sulfate plate stock, recycled coated soft white, and recycled ground wood furnish such as newsprint or the like. In one embodiment, the blend comprises about 25-50 wt. % recycled solid bleached sulfate plate stock, about 25-50 wt. % recycled coated soft white, and about 15-25 wt. % recycled ground wood furnish. The furnish blend is repulped with minimal mechanical refining, is treated with steam injection for hydrating and softening the fibers, and is formed into a web that is pressed, dried, and soft calendered. The caliper of the resulting stock is about 7 to 9 points.

Description

BACKGROUND OF THE INVENTION [0001] The invention relates in general to papermaking, and in particular relates to the manufacture of paper suitable for use as ticket stock used for making redemption tickets of the type commonly dispensed from automated machines in game arcades and the like. [0002] Game arcades often have electronic games that dispense redemption tickets as a reward for having played the game well. Depending on the game score achieved by the player, the game machine dispenses a different number of tickets. The tickets typically can be redeemed for prizes such as toys, stuffed animals, candy, and the like. The game machines generally employ an automated ticket dispenser that dispenses a number of tickets based on the game score. The tickets are supplied in the form of a roll of interconnected tickets separated from one another by perforations. The tickets usually have a printed bar code on one side and may have other indicia and / or graphics on the opposite side. The au...

AI Technical Summary

Benefits of technology

The invention provides a ticket stock and manufacturing process that uses a pulp made from recycled furnishes, starch, and clay or other opacifier. The pulp is formulated by blending recycled furnishes and adding starch and clay. The ticket stock has a caliper of 7-9 points, with a smooth surface and good printability. The manufacturing process involves repulping the recycled furnishes with minimal mechanical refining, adding starch and clay, forming a wet web, dewatering and pressing it in a press section, and calending it to a smooth surface. The technical effects of the invention include improved stiffness, reduced linting and dusting, and enhanced opacity of the ticket stock.

Problems solved by technology

Currently available ticket stocks do not always achieve all of these desirable characteristics.

Such coated SBS ticket stock generally does not have a desirable soft feel in the hand.

However, reducing the caliper generally has an adverse impact on some of the other desirable characteristics.

There is also a certain caliper threshold below which the tickets do not have a good “feel” in the hand, as being too flimsy or insubstantial.
