Yoga Pants in the Print World?

Life without pockets? We’d all be wearing yoga pants. (Eww, what a thought.)

Welcome to this month’s issue of our continuing Helpful Hints series. If you have any comments about today’s topic or suggestions for future ones, please let us know by e-mailing Kevin Rickard.

Pockets are useful in clothing. Pockets are useful in printed pieces too. Here are three examples:

These are examples of the cost- and timesaving recommendations your customers are craving. Not yoga pants.

The Latest Rickard Bindery Video

Here’s a 94-second video of Rickard Bindery’s estimating team leader, Gary Junge, showing some examples of printed products with welded seam pockets, converted in our bindery.

The Big Five:

  1. Basics. Resin-based permanent glues are applied cold and provide a good bond with a relatively small amount of residue. Permanent glues forming pockets need to bite into paper, so the harder the surface, the more difficult it is to penetrate the sheet and create good adhesion.
  2. Benefits. The gluing and folding of pockets go hand-in-hand. Many direct mail projects require a combination of seam (permanent), remoistenable and ez-release glue, often all three. Common applications for welded seam pockets include envelopes, BREs (business reply envelopes), carriers for PIs or delivery mechanisms for the consumer product itself.
  3. Variants. When combatting tricky adhesion issues caused by ink, varnish and other paper coatings present in adhesion areas, sometimes hot melt seam glue can be substituted for cold.
  4. Max & mins. A glue dot or line will spread, no matter how small or thin it is. Practically speaking, glue usually spreads more than 1/8″. Highly efficient layouts for maximum paper usage might cause “bricking” problems if trim-out glue margins are too narrow to account for glue spread.
  5. Shop talk. Knock out varnish, inks and other coatings on both sides of where glue adheres. Although some manufacturers have developed hot melts that can work with certain varnish-covered products, most glues, hot, cold or otherwise, have difficulty bonding to paper coatings. If planning to apply glue to a coated piece, check with Rickard Bindery to determine the appropriate glue for your product with a welded-seam pocket.

The Rickard Bindery Welded Seam Gluing Advantage

At Rickard Bindery, many of our welded seam gluing jobs are performed inline with other bindery processes. For example, we may apply remoistenable glue, perforate the sheet, apply seam glue to form a pocket, fold it (roll folds, accordions and gatefolds), apply wafer seals and keep the job in mail-sort order … all inline.
