1. Function difference:
Heavy duty cartons are used in a wide range of applications. Chemicals, auto parts, cabinetry equipment, medical equipment, metal parts and major high-duty products are all suitable for heavy-duty carton packaging; regular cartons are most commonly used for product packaging we see every day. In this process, you only need to solve the parcel items, such as small daily necessities such as clothes, shoes, tissues and fruits.
2. Raw material difference
Ordinary cartons are mostly three to seven-layer cartons, which are composed of low-gram face paper, core paper (that is, corrugated paper in the middle) and inner layer paper. Some manufacturers can also produce ordinary cartons with 440 grams of face paper, but their performance is not as good as that of 440 grams of imported kraft paper for heavy cartons, and the carrying capacity is relatively small.
Heavy cartoons usually have more than 5 layers. The surface paper is 250g/440g kraft paper imported from the United States. The core paper and intermediate paper are high weight corrugated boards. The inner paper can be determined according to the weight of the customer's product and the stacked layers during transportation. In one sentence, it's high-weight, high-strength, and multi-layered.
Heavy-duty corrugated packaging provides the strength, stability and insulation needed to meet the physical requirements of your supply chain, whether by road or air. Packaging design combined with the selection of suitable materials ensures your product arrives at its destination in top condition.
Heavy-duty corrugated packaging: There are five-layer cartons and seven-layer cartons. Most of the cardboard materials are imported kraft cardboard, and the weight is: 440 grams of imported kraft cardboard, 330 grams of imported kraft paper, 180 grams of high-quality core paper, and 100 grams of heavy-duty carton, made of 230 grams of kraft cardboard. The mine types are mainly composed of A mine, AA mine and AAA mine. These materials and pit types are mainly used for large-scale machinery and equipment, and the load-bearing capacity can reach more than 2 tons.
