I. Preparatory Requirement Confirmation & Document Preparation
Clients shall confirm in advance the overall dimensions, material type, visual style, order quantity and special finishing requirements for custom tea bag packaging. Production specifications, delivery lead times and cooperation details are fully clarified meanwhile. In addition, clients need to prepare complete production documents, including packaging structure parameters, marking positions of decorative elements and product compliance texts. This helps finalize the production plan efficiently and arrange subsequent manufacturing procedures smoothly.
II. Submission of Final Print-Ready Files
To ensure smooth printing production, clients are required to provide completed design files that meet professional printing standards. The files must contain bleed lines, die-cut lines, safe margins, standard printing color modes and high-definition images. All areas for special processes such as hot stamping, lamination and embossing shall be clearly marked. Clients shall independently check and confirm all texts, content and layouts. Once the files are finalized, we will proceed with technical verification and printing plate making.
III. Food-Grade Raw Material Selection & Centralized Stock Preparation
Tea bag packaging belongs to food-contact packaging, so we only adopt raw materials that comply with international food safety standards. We select qualified materials including food-grade white cardboard, moisture-proof coated paper, eco-friendly kraft paper and food-grade composite paper according to order demands. Environmentally friendly plant-based inks, non-toxic adhesives and certified lamination materials are fully applied in production. All raw materials will be inspected before warehousing and stored in a moisture-proof environment, ensuring high toughness, waterproof performance and hygienic quality for long-term tea storage.
IV. Plate Making & Mass Printing Production
Based on the finalized design files provided by clients, we produce customized printing plates and die-cutting tools, followed by professional machine commissioning. Our technicians calibrate registration accuracy, ink density and color balance. A digital proof will be delivered to clients first for color and visual effect confirmation. After sample approval, formal mass production will be launched. Continuous on-site workshop inspection effectively avoids color difference, ink stains, missing printing and registration deviation, delivering clear, consistent and unified printed results for all batches.
V. Custom Finishing & Secondary Processing
After basic printing, we provide a full range of customized finishing services as requested, to upgrade the texture and brand value of custom tea bag packaging, including matte or glossy lamination, partial gold and silver hot stamping, screen cold stamping, debossing, embossing, spot UV coating and texture finishing. These advanced treatments greatly enhance water resistance, scratch resistance and friction durability, upgrading product grade and brand recognition. Tiny texts, delicate patterns and process joints are finely processed to balance exquisite appearance and long service life.
VI. Precision Die Cutting, Creasing & Edge Trimming
Printed and finished semi-finished products will be sent to the die-cutting workshop. Custom dies are used for shaped cutting and folding creasing in strict accordance with client design dimensions. Excess materials are removed and burrs are trimmed to ensure smooth edges. Reasonable creasing lines enable easy subsequent folding. All semi-finished products are standardized uniformly to prevent size deviation and deformation, maintaining consistent overall appearance of bulk goods.
VII. Box Gluing & Final Assembly
Box gluing and assembly are carried out mechanically or manually based on packaging structures. Precise positioning and controlled adhesive dosage prevent glue overflow, peeling and misalignment. After folding, gluing and shaping, boxes feature firm and rigid structure with flexible opening and closing performance. They are perfectly suitable for tea bag filling, sealing and market display, keeping stable shape and strong damage resistance during use.
VIII. Multi-Layer Quality Inspection & Defect Sorting
After assembly, full-range manual quality inspection will be conducted for every batch. Our team inspects printing quality, finishing durability, adhesive firmness, surface condition, breakage, stains and size errors. Defective products will be isolated and eliminated uniformly. Only qualified, defect-free and structurally stable products will be approved for shipment. Strict multi-stage quality control stabilizes factory output quality and reduces after-sales problems.
IX. Protective Packing, Counting & Shipment Delivery
Qualified finished goods are sorted and counted by style and quantity. Double-layer protective packing with moisture-proof film and hard cartons is adopted to avoid dampness, collision and abrasion during transportation. After verifying order quantity, product information and delivery details, we arrange logistics and provide delivery notes to guarantee on-time delivery. We support repeat orders and mass re-production to steadily meet all customized packaging demands of custom tea bag packaging.https://www.heyuprinting.com/color-box/gift-box/cardboard-tea-box.html
