Hole Design Hamburger Box

The Hole Design Hamburger Box supplied by Qingchen manufacturer is made through a one-step die-cutting process using food-grade biodegradable coated white paper. It comes with four-sided self-locking clasps and is shipped as a flat folded sheet, significantly reducing storage and logistics costs. The inner wall is coated with a water-based food oil-resistant layer, which can effectively prevent the penetration of salad sauce, red oil, and meat pie juice for a long time. The outer side of the box supports full-color printing customization, allowing for the complete printing of brand logos, store slogans, and distinctive illustrations. The ink only adheres to the outer layer and does not come into contact with the food. The entire material has passed food contact safety testing.

Differential Advantage

Unlike the common problem of unsealed hamburger boxes on the market that cause bread to become soggy and generate moisture, this Hole Design Hamburger Box can quickly expel the hot steam inside the box. It meets the triple requirements of dust prevention, sauce retention, and heat dissipation. It can be purchased in bulk by offline hamburger stores, food delivery merchants, and cross-border catering packaging wholesalers. At the same time, personalized adjustments can be made to size, hole position, and printed patterns.

Key attributes

Manufacturing process

1. Food-grade raw paper material screening and pre-treatment

The factory only purchases virgin coated white card paper that meets food contact standards. After the raw materials are storage entry, sampling tests for fluorescent agents, heavy metals, and temperature resistance are conducted first. Recycled waste paper and inferior thin paper are removed. Qualified raw paper is uniformly treated with single-sided water-based anti-oil coating, which is then left to stand and solidify to ensure uniform coating without peeling. This ensures that oil leakage and odors are completely prevented from the source.

2. Numerical control die-cutting and breathable hole integrated molding

Using fully automatic die-cutting equipment, the box body contour is cut, the snap tab creases are pressed, and the breathable holes are precisely drilled simultaneously. The box body is formed in one step without the need for secondary manual drilling. The size and position of the holes have been optimized through multiple meal-out measurements, ensuring that they are neither too large to leak dust or sauce, nor will they cause steam to be trapped and not escape smoothly. The crease depth is uniform, making it easier for the store to fold and form the box.

3. Environmental-friendly inkjet printing process

According to customer requirements, four-color offset printing is performed. The printing area is limited to the outer layer of the box body, while the inner wall remains blank and does not come into contact with the ink. After printing, the material is sent to the drying channel to fully evaporate the ink residue, preventing the ink from adhering to hands or food. After drying, it is left to cool and prevent the pattern from sticking together when stacked.

4. Locking tab edge reinforcement heat treatment

After printing, the sheet enters the heat pressing station. The box body snap tab and side edge edges are lightly heat-set for mild heat stabilization treatment to enhance the toughness of the edges. They will not break easily even after repeated opening and closing, and will not spread apart when stacked and stored.

5. Sorting, folding, packaging and storage

Each batch of sheets is inspected manually, and defective products with skewed holes, die-cut burrs, color bleeding during printing, or damaged coatings are removed. Qualified products are uniformly laid flat and folded, packed in standard outer boxes according to fixed quantities, labeled with model, material, batch inspection number, and classified for storage. Hole Design Hamburger Box is available for immediate shipment upon request.

Key selling points
