Materials Management and Handling

Once a printed sheet destined to finish as a corrugated container or POP unit comes off the press, its journey has only just begun. Before reaching its final destination, that sheet has to endure stacking, wrapping, loading and shipping. A lot can happen in that process that has the potential to damage an otherwise perfect job. That’s where Garvey’s extra efforts to maintain quality control really pay off.

Precise Climate Control

Exacting substrate storage climate control is vital to the condition of the finished job, with relative humidity being a critical factor. When paper is stored under dry, low humidity conditions, moisture from the outer layers and edges of the stacks escapes into the air. Because the moisture loss is greater from the edges than from the center of the stack, the result is curled stock and uneven moisture content, leading to printing and paper handling problems.

The same dry air will cause problems with printed sheets. Not only is curling an issue, but when dry sheets are die cut and then folded as they are applied to corrugated, cracking, wrinkling and tunneling can often occur, making the sheets useless.

But too much relative humidity can cause loss of quality too—such as sheets not adhering to the boxes. To ensure the environmental conditions necessary to maintain our quality standards, The Garvey Group commissioned a custom-designed, state-of-the-art Nortec® humidity and climate control system in the stock storage, pressroom and shipping areas. It’s worth noting that this system was built specifically with our large format printing operation in mind. And to confirm that the climate control is doing its job, stacks and individual sheets are constantly moisture-wanded as a spot check.

Because Garvey Group managers understand the complete packaging manufacturing process, they see that great care is taken with the handling of a customer’s job after it comes off press. Sheets are stacked square and tight, and carefully wrapped, banded and loaded, all to make sure that on arrival, there is no problem or delay that could impede the customer’s schedule.
