Comparing Different Materials Used in Wax Coated Boxes

The protective performance, application scenarios and environmental attributes of wax coated boxes depend on the combination of base paper and coating wax materials. Different material combinations result in significant differences in the moisture resistance, pressure resistance, food safety and biodegradability of the boxes. As a global eco-friendly packaging solution provider with more than 20 years of experience in the packaging industry, Richer Group has a profound understanding of the material selection logic of wax coated boxes. Relying on the R&D capability of its subsidiary Xiamen Greenlife Eco Tech Co., Ltd. and the production advantages of Xiamen Richer Plastic Co., Ltd., it has created highly adaptable material combination solutions for different scenarios such as logistics transportation, fresh food and retail packaging. This article will conduct an in-depth comparative analysis of the mainstream base papers and coating wax materials of wax coated boxes, and provide professional references for enterprises to select suitable materials for wax coated boxes in combination with Richer Group's practical application experience.

The base paper of wax coated boxes is the foundation of the structural strength of the cartons. The mainstream food-grade kraft paper, corrugated paper and white cardboard have their own advantages and disadvantages in physical properties and application scenarios, and they are also the core material selection directions for Richer Group when customizing solutions for customers. The specific comparisons are as follows:

As the main base paper of Richer Group's wax coated boxes, food-grade kraft paper is made of virgin wood pulp, with both toughness and food safety, no harmful substances precipitated, and in line with FDA food contact standards. Its grammage is mostly 200-400g, with good stiffness, strong tear resistance, excellent wax layer adhesion and more stable moisture and water resistance, suitable for the packaging and transportation of fresh food and processed food. The disadvantage is that the surface flatness is general, the visual effect of custom printing is slightly weak, and it is suitable for scenarios that focus on protection rather than appearance display.

Corrugated paper is divided into single corrugated and double corrugated. Its core advantage is good cushioning and shock resistance. Combined with wax coating, it can improve the extrusion resistance of the carton while preventing moisture, which is the core base paper of Richer Group for long-distance logistics transportation and fragile product packaging. Its disadvantages are slightly higher weight, which will increase a small amount of logistics cost, and higher requirements for wax spraying process, which is prone to uneven coating. Relying on 8 professional printing and coating equipment, Richer Group can realize uniform wax spraying on corrugated paper and solve this industry pain point.

White cardboard has a smooth surface and strong print adaptability. After wax coating treatment, it has basic moisture resistance. Richer Group mainly uses it for retail gift boxes and lightweight food packaging, taking into account both protection and brand display effects. Its disadvantages are poor toughness and tear resistance, easy deformation under excessive stacking pressure, and higher cost than kraft paper, making it unsuitable for long-distance sea shipping and heavy cargo packaging scenarios.

Coating wax material is the key to determining the moisture resistance and environmental attributes of wax coated boxes. In accordance with the compliance requirements of the international market and customer needs, Richer Group mainly selects three types of materials: food-grade paraffin wax, microcrystalline wax and bio-based biodegradable wax. The characteristics and application scenarios of the three are significantly different:

Food-grade paraffin wax is the most classic wax coating material with a moderate melting point and good fluidity. It can form a dense water barrier film on the surface of paper materials, with excellent moisture resistance and low cost, which is the basic choice of Richer Group for conventional logistics and general food packaging. Its disadvantage is poor temperature resistance, easy to melt in high-temperature environments, and not suitable for transportation in tropical regions or high-temperature storage scenarios.

Microcrystalline wax has a higher melting point and denser structure, and its temperature resistance and friction resistance are far superior to food-grade paraffin wax. The wax layer is not easy to fall off after adhesion, suitable for tropical sea shipping and transportation scenarios with high-friction loading and unloading. Richer Group uses it for cross-border transportation packaging in high-temperature regions such as Southeast Asia and the Middle East. Although the cost is slightly higher than food-grade paraffin wax, it can greatly reduce the problem of carton protection failure caused by wax layer melting.

Independently developed by Xiamen Greenlife Eco Tech Co., Ltd., a subsidiary of Richer Group, bio-based biodegradable wax is made of plant starch and biomass. Combined with biodegradable paper, the whole box can be completely biodegraded, complying with international environmental standards such as EN13432 and ASTM D6400. Its moisture resistance is equivalent to that of food-grade paraffin wax, and it also takes into account food safety and environmental protection. It is the core material selection of Richer Group for markets with stringent environmental regulations such as Europe, America and Australia, and also the first choice for enterprises to build a green brand image. The only disadvantage is that the cost is higher than traditional wax materials.

Based on the characteristics of different base papers and wax materials, Richer Group has formulated highly adaptable material combination solutions for different scenarios with more than 20 years of industry experience. At the same time, relying on a 13,000 square meter modern production base, 24 film-blowing machines and professional coating equipment, it realizes large-scale and standardized production of various materials. The 98.7% first-time inspection qualification rate ensures the stability of product quality:

In addition, all materials of Richer Group have passed international certifications such as ISO9001, BSCI and FSC, adapting to the packaging regulations of most countries and regions in the world, and helping customers' products successfully complete cross-border circulation.

The material selection of wax coated boxes is not a single "selection of the best", but an "adaptation" according to the use scenario, transportation environment and environmental requirements. The base paper determines the structural strength and basic adaptability, while the coating wax material determines the core protective performance and environmental attributes. With profound R&D capabilities, advanced production equipment and global market experience, Richer Group can not only accurately control the characteristics of various materials for wax coated boxes, but also provide customers with customized material combination and production solutions, making the performance of wax coated boxes highly consistent with the actual needs of customers. Under the trend of the packaging industry moving towards greenization and customization, Richer Group has become a reliable partner for enterprises in the procurement of wax coated boxes with its professional material selection capability, helping enterprises achieve a triple improvement in the protection, compliance and economy of packaging.
