Heavy duty brown paper bags
Maximum Strength for Heavy Merchandise
These heavy duty brown paper bags use imported kraft board with 200 gram, 250 gram, and 300 gram options. Common sizes are 30 by 40 by 12 centimeters, 35 by 45 by 15 centimeters, and 40 by 50 by 18 centimeters. The handles are thick paper rope or cotton rope with reinforced strength. For printing, we use offset printing for four-color or spot colors. We also offer foil stamping in gold or silver. These heavy duty brown paper bags can hold 10 to 20 kilograms. The bottom uses a square base with an extra paperboard reinforcement layer. The surface can have glossy lamination, matte lamination, or partial UV coating.
These heavy duty brown paper bags are the thickest option in our paper bag line. The 300 gram kraft board is very rigid and feels substantial in hand. The weight capacity is strong enough for heavy merchandise. The reinforced bottom board is a thoughtful design. Regular paper bags can puncture at the bottom when loaded with heavy items. But with the added board, the base is very stable. The printing quality is excellent. Offset printing can produce four-color designs. Foil stamping on thick paper looks very premium. Lamination gives a smoother surface and improves water resistance.
Heavy Paper Handling and Bottom Reinforcement
Our bag making machine can handle 300 gram thick paper. This weight requires special equipment. Regular bag machines cannot process paper this thick. Our machines have been upgraded with stronger feed and folding mechanisms. The bottom reinforcement board is added automatically during bag making. The machine inserts the board between the two bottom layers and presses them together. The board stays in place without being visible. But you can feel the solid base when you hold the bag. Foil stamping is done after printing. Our foil stamping operators control temperature and pressure carefully. This ensures clear edges and no foil flaking.
These heavy duty brown paper bags are suitable for shoe box outer packaging, wine and liquor gift packaging, electronics, premium cosmetics, exhibition VIP bags, and heavy merchandise shopping. The quality and weight capacity make them suitable for premium and heavy applications. We support OEM and ODM customization. You can choose different weights, sizes, and surface treatments. The minimum order quantity is 500 pieces. Sample development takes 5 to 10 days. Mass production takes about 20 days.
