Guangdong Guowei Guanli: 17 Years of Dedication to Replacing Plastic with Paper, Case Study on Bulk Supply of Brown Bags Paper

Since its establishment in Dongguan in 2007, Guangdong Guowei Guanli New Materials Co., Ltd. has been dedicated to the field of replacing plastic with paper for 17 years. With its unwavering commitment to sustainable packaging and accumulated technical expertise, the company's brown bags paper products have become the preferred choice for many industries seeking to transition to environmentally friendly solutions. The following three bulk supply cases illustrate the advantages and value of brown paper bags in practical applications.

Chain Supermarket: A Sustainable Shopping Bag Solution with Monthly Sales of 500,000 Units

A national chain supermarket faced challenges in packaging transformation under the “plastic restriction order,” with traditional plastic bags restricted and ordinary paper bags lacking sufficient load-bearing capacity and being cost-prohibitive. Guangdong Guowei Guanli customized brown bags paper for them using 80g kraft paper material, enhanced with embossing technology to increase durability, with each bag capable of holding up to 5 kilograms, meeting daily shopping needs.

 

In bulk supply, the company achieved a daily production capacity of 20,000 units through automated production lines, with a stable monthly supply of 500,000 units, keeping the cost per unit below 0.25 yuan. After the supermarket adopted these bags, they not only complied with environmental policies but also enhanced the brand's image due to the “biodegradable shopping bag” label, resulting in an 8% increase in consumer repurchase rates compared to before. Additionally, the recyclable and reusable nature of the brown paper bags makes them an important symbol of the supermarket's commitment to sustainable development.

 

Agricultural Product E-commerce: Moisture-proof and Damage-resistant Applications in Fresh Produce Delivery

Fresh agricultural products have extremely high requirements for moisture-proof and damage-resistant packaging. A leading agricultural e-commerce platform once faced environmental controversies over plastic packaging. Guangdong Guowei Guanli designed brown paper bags for them using PE lamination technology, with an inner layer of food-grade film. This retains the breathability of kraft paper while providing leak-proof functionality, perfectly suited for the delivery needs of fruits, vegetables, and dried goods.

 

In bulk supply, the company customizes sizes based on different product categories, ranging from 30×40 cm to 50×70 cm, with an average daily supply of 30,000 units, ensuring the e-commerce platform's “next-day delivery” logistics efficiency. The e-commerce platform reported that after switching to brown bags paper, packaging damage rates dropped from 12% to 3%, customer complaints decreased by 60%, and annual packaging costs were reduced by over one million yuan due to packaging costs being 15% lower than biodegradable plastic bags.

 

Industrial components: Balancing load-bearing capacity and cost in heavy-duty packaging

Industrial component packaging often relies on thick plastic bags or wooden boxes, which are costly and environmentally harmful. A certain automotive component manufacturer achieved significant results by replacing these with brown bags paper. Guangdong Guowei Guanli customized double-layer kraft paper brown bags paper for them, reinforced with adhesive to enhance seam strength, capable of carrying 10 kilograms of metal parts, meeting workshop turnover and transportation requirements.

 

In the bulk supply solution provided by the company to the manufacturer, a continuous production model using roll paper was adopted, delivering 100,000 units weekly, with each unit costing only one-fifth of a wooden box. After six months of use, the manufacturer reduced packaging waste by 70% and saved 30% in warehouse space, validating the feasibility of brown paper bags in industrial packaging.

Over the past 17 years, Guangdong Guowei Guanli has consistently focused on “carbon reduction and environmental protection, cost reduction.” In addition to brown paper bags, products such as custom paper bags and packaging paper bags are widely used in industries like food and retail. In the future, the company will continue to optimize production processes to provide sustainable Packaging Solutions that combine environmental friendliness and cost-effectiveness for more global enterprises, driving the industry-wide transition from plastic to paper.​
