Driven by both the ongoing tightening of environmental policies and the growing awareness of environmental sustainability among consumers, paper packaging bags are increasingly becoming the mainstream alternative to traditional plastic bags. Qingdao Teyi Plastic Packaging Co., Ltd., located in Jimo District, Qingdao, has set a benchmark for the industry’s green transformation through its innovative practices in the field of paper packaging.

**Technological Breakthrough: From Single Material to Functional Composites**
Since expanding its business scope in 2020, Qingdao Teyi Plastic Packaging Co., Ltd. has shifted its R&D focus to the upgrading and iteration of paper packaging bags. The company uses white kraft paper made from 100% virgin wood pulp as its core material and, through a specialized treatment process, achieves water- and oil-resistant performance without the need for lamination, successfully applying this technology to the takeout packaging sector. For example, in collaboration with a local chain restaurant brand, it launched a “zero-plastic takeout bag” that incorporates a biodegradable plant-based coating. While preserving the paper’s breathability, this coating reduces oil‑stain penetration by 90% and extends the bag’s service life to three times that of conventional paper bags.

**Market Response: A Surge in Orders Driven by Policy**
With the implementation of Qingdao City’s “Action Plan for Further Strengthening Plastic Pollution Control,” Teyi Company’s production capacity for paper packaging bags is expected to exceed 50 million units per year by 2025. According to the company’s management, in the first quarter of 2026 it has already secured custom orders from clients such as Starbucks and Hema Fresh. Among these, a magnetically sealed paper bag designed for a coffee brand incorporates recyclable magnetic inserts to enable reuse, reducing the cost per bag by 15% compared to conventional plastic bags. In the farmers’ market sector, the company’s lightweight, biodegradable paper bags—priced at just RMB 0.03 each—have successfully replaced 80% of non‑degradable plastic bags thanks to their cost advantage.

**Industrial Collaboration: Building a Green Packaging Ecosystem**
Teyi Company is collaborating with local paper manufacturers in Qingdao to build an end-to-end “forest-to-shelf” value chain. By using FSC‑certified base paper and optimizing cutting processes to minimize edge‑trim waste, the company has reduced the carbon footprint of each bag by 40% compared with the industry average. Its newly built digital factory is equipped with an AI‑powered quality‑inspection system that monitors heavy metal levels in printing inks in real time, ensuring that food‑contact‑grade paper bags meet the requirements of GB 4806.8‑2022.

Industry experts note that Qingdao Teyi’s experience demonstrates that the widespread adoption of paper packaging bags must balance functionality with cost-effectiveness. With breakthroughs in bio-based coatings and nano‑waterproofing technologies, paper packaging is transitioning from an “emergency substitute” to a “mainstream packaging solution,” offering a replicable “Qingdao model” for the industry’s green development.
