Box Mfg. – Set-Up PaperDescription
Code 4240 applies to employers engaged in manufacturing cardboard packaging boxes distributed in an assembled state (not flat state) with tops or closures in place. These products are commonly used to package candy, drugs, jewelry, shoes, stationery, hats, hosiery, shirts, and other similar products. The materials used in paper box manufacturing normally include cardboard stock (also referred to as paperboard, box board or pasteboard), rolls of flat finish or coated paper, staying tape, lace or plain paper used for the flat inside section of the box, paste, gum or glue, ink, type, plates, labels or wrappers.
Cardboard stock is received cut to size, scored and creased to box dimensions. Employees cut out box corners, bend the box sides (flanges) and secure the box corners with a “corner stayer,” which pastes gummed tape or paper to the corners of the box. Next, in a process called “stripping” they automatically glue paper to the sides of the box. The box tops and bottoms are spread with paper which, in many instances, has been previously printed or embossed. This process often involves topping or wrapping machines. When boxes are to be paper-lined, “flyleaf” or “lace paper” is gummed on the edge and pressed to the inside of the box. Thumbhole cutters punch out the thumbholes for the box. Employees set type or plates in presses, print the labels and hand or machine paste the labels onto the boxes. Lastly, the boxes are examined, closed with covers, bundled and shipped.
This classification also includes manufacturing set-up or assembled boxes made of acetate or similar plastic sheet materials if the manufacturing operations are comparable to those associated with the manufacturing of cardboard boxes as described above.
