As the global supply chain transitions rapidly toward a circular economy, flexible packaging must evolve. Guangdong Tianchen Printing Co., Ltd. leverages over two decades of high-precision rotogravure expertise to bridge the gap between ecological responsibility and robust industrial barrier performance. Our custom ODM biodegradable resealable bags present a definitive technical answer to modern sustainability mandates.
Utilizing high-performance compostable bioplastics (PLA, PBAT, and PHA) tailored to replicate the high-barrier performance of traditional oil-based laminates.
From complex flat-bottom gusset structures to specialized moisture-proof slide-to-lock zippers, engineered exactly to application requirements.
Strictly complying with ASTM D6400, EN 13432, and heavy metal restrictions, supporting verified claims of home and industrial compostability.
In previous iterations of eco-packaging, brands faced a harsh compromise: choose biodegradable substrates and accept poor barrier performance, or use fossil-derived multi-layer plastics to preserve shelf life. The modern flexible packaging industry has broken this dichotomy. Through advanced multi-layer lamination, bio-derived elements can now match conventional films in oxygen transmission rate (OTR) and water vapor transmission rate (WVTR).
The rapid expansion of the organic food, premium dry goods, cosmetics, and agricultural sectors has spurred immense demand for high-strength, resealable pouches that leave zero microplastics behind. Brands are no longer treating green packaging as a public relations option; strict legislative pressures across the European Union (CEFLEX guidelines) and North America require traceable sustainable materials to avoid massive extended producer responsibility (EPR) taxes.
Operating in the heart of Guangdong's manufacturing cluster, our production complex integrates advanced intelligent controls with vertical manufacturing lines to supply stable, high-barrier compostable materials to the global market.
Our extrusion and co-extrusion blown film lines are integrated with continuous laser thickness-measuring systems. This ensures uniform tensile strength, preventing material failures or zip-lock separation during heavy commercial packaging runs.
We employ automated eco-solvent and water-based ink printing matrices. These dynamic systems allow precise color-matching and ultra-crisp resolution of detailed graphics without releasing volatile organic compounds (VOCs).
Each batch of biodegradable film undergoes immediate barrier gas testing, puncture resistance validation, and thermal seal-strength tests. These comprehensive protocols ensure our bags consistently survive strict marine, land, and aerial shipping cycles.

Innovation, Internationalization, Integration, Intelligentization
Guided by our core four "IN" concepts, we have forged a clear development path and maintained steady growth in the competitive global market. The first is "Innovation" – we persist in investing in R&D, upgrading printing technologies and processes, and developing eco-friendly, high-performance packaging materials to keep pace with industry trends and client demands. The second is "Internationalization" – we adhere to global standards in production and management, obtain international certifications, and expand our global service network.
The third concept is "Integration", which refers to our one-stop service model integrating design, printing, laminating, converting, and quality inspection. By optimizing the industrial chain layout, we streamline production and reduce costs. The fourth is "Intelligentization" – we have introduced advanced intelligent production equipment and digital management systems, realizing automated operations in key links such as color matching and quality control.
Under the strategy of "innovation and transformation, integrated operation and steady growth", we firmly uphold the concept of sustainable development. We actively adopt green production technologies, reduce energy consumption and environmental impact, and strive to achieve a win-win situation between economic benefits and social responsibility. Our goal is to become a first-class enterprise in the global mainstream packaging market.

Addressing specific performance targets across distinct global market segments
Coffee beans, loose teas, protein powders, and artisanal snacks require absolute barrier protection to prevent oil oxidation and maintain crisp textures. Our customized biodegradable resealable flat-bottomed pouches preserve original aromas, block light degradation, and offer structural stability on retail shelves.
With the rise of natural, zero-waste cosmetics, facial sheets, and hygiene rolls, brands must utilize packaging that aligns with their organic formulas. Our plant-derived moisture-resistant films and custom closure bags protect contents from external bacterial contamination.
For biological seeds, eco-friendly fertilizers, and premium feed products, our heavy-duty bio-derived gusset and dry bags withstand chemical reactions and physical punctures during long supply-chain journeys.
Sourcing biodegradable materials on a large scale requires close alignment with regulatory certifications, reliable lead times, and deep cost-engineering expertise. Working directly with a vertically integrated Chinese packaging facility allows brands to bypass intermediaries, stabilize material costs, and secure consistent access to high-quality raw materials.
Our facility provides comprehensive support to help international procurement teams navigate complex customs inspections, compliance documentation, and ocean cargo loading protocols. By consolidating design, printing, and bag production under a single roof, we compress lead times and help clients lower their inventory carrying costs.
Yes. By layering high-barrier PLA and PBAT compostable films with advanced metallized barrier technologies, we can restrict oxygen transmission to less than 1.5 cc/m²/day and water vapor migration to less than 2.0 g/m²/day. This ensures dry goods, coffee, and protein powders remain perfectly fresh throughout their commercial shelf life.
Our raw materials and laminated films conform fully to global biodegradable benchmarks, including ASTM D6400 (US standard for compostability) and EN 13432 (European compostability certification). They undergo strict third-party laboratory analysis to verify they leave behind zero toxic chemical residues or persistent microplastics.
Our custom-engineered zippers are formulated with high-grade, heat-resistant PLA blends. They are built to resist heat seal stress during high-speed production runs and perform reliably in typical humid retail settings. They will only decompose when exposed to active microbial compost conditions.
When stored in their original protective cartons under cool, dry conditions (ideally 15–25°C with less than 50% relative humidity), our biodegradable resealable bags retain their full tensile strength, flexibility, and zipper seal performance for up to 12 to 18 months prior to filling.
We provide full-service, high-speed rotogravure printing in up to 10 distinct colors, using high-resolution machinery. This supports detailed photographic graphics, complex geometric layouts, and dynamic brand logos. We exclusively use eco-friendly water-based and soy inks to maintain the compostability of the entire package.
