Enhance your company’s communications with China’s professional Envelope printing 5100 seconds printing. We produce customizable envelopes for business, marketing, secure correspondence, and large-scale orders, ensuring every piece represents your brand.
When customizing envelopes in China, the core parameters directly determine the product's durability, professional appearance, mailing efficiency, and brand impact. Key factors include size specifications, paper material and weight, printing color options, surface finishes, and sealing structure. Proper selection helps balance quality and cost while matching local business needs (such as corporate correspondence, e-commerce packaging, or premium invitations). The table below summarizes the most practical core parameters with China-relevant recommendations.
| Parameter Category | Common Options | Explanation & China Local Recommendations |
|---|---|---|
| Size Specifications | DL (220×110mm), ZL (230×120mm), C5 (229×162mm), C4 (324×229mm) | DL and ZL are the most popular in China for business letters, invoices, and notices; C4 fits unfolded A4 documents; tolerance usually ±1mm to avoid mailing returns |
| Paper Material & Weight | 120g–140g kraft/white kraft paper, 100g–157g coated paper, 80g–120g recycled/offset paper | Kraft paper offers strong tear resistance, ideal for China's humid climate in e-commerce shipping and document protection; coated paper delivers vibrant colors for branding |
| Printing Color Scheme | Single color (black/red/blue), CMYK full color, Pantone spot color | CMYK full color is recommended for China company logos and promotional designs with rich, accurate reproduction; single color is more economical for low-volume orders |
| Surface Finishes & Post-Processing | Gold/silver foil stamping, spot UV, matte/gloss lamination, embossing, die-cutting (custom shapes) | Foil stamping + lamination creates a premium look for China wedding or event invitations; embossing adds tactile depth but requires 200g+ paper stock to prevent cracking |
| Sealing Structure & Closure | Peel-and-seal (with release liner), string-and-button, moisture-activated gum, tamper-evident self-adhesive | Peel-and-seal provides strong, secure closure for China confidential documents; string-and-button allows easy re-opening, perfect for gift envelopes and repeat-use scenarios |
With growing demand for green packaging in China, eco-customizable envelope types use recycled, plant-based, or biodegradable materials while maintaining professional quality and printability.
| Envelope Type | Sustainable Features | China Green Customization Notes |
|---|---|---|

| Plantable Seed Announcement | Embedded wildflower seeds | Ideal for China promotional giveaways; plant after use for brand memory |
| FSC-Certified Booklet | Forest Stewardship Council certified paper | Meets China corporate sustainability reports; supports full-color branding |

| Water-Soluble Closure Eco | Non-plastic gum, recyclable adhesive | Fully recyclable for China zero-waste initiatives |
