If you're new to customizing plastic packaging bags and confused by all the surface printing processes on the market-like matte, glossy, UV, hot stamping (gold or silver), aluminum leaking, laser, internal printing, etc.-this article is for you.As a local Chinese plastic packaging bag factory, we offer all these printing services, helping you avoid mistakes and make the best choice.
1. Basic Texture: Matte Printing & Glossy Printing (Most Common, Cost-Effective)
These two are the most basic and common surface processes. The main difference is the gloss of the bag's surface-you can tell them apart at a glance, making them the first choice for beginners.
Matte Printing: The surface has no gloss, feels smooth and matte (like sandpaper), doesn't reflect light or glare. It looks low-key and high-end, with clearer printed patterns (no glare to hide details). It's also dirt-resistant and doesn't show fingerprints easily, so it won't look old quickly. Suitable for food, daily necessities, gifts, etc.-like snack bags, skincare sample bags.
Glossy Printing: Opposite to matte, the surface is shiny and smooth, reflects light clearly, making patterns look brighter and more eye-catching. It has high color reproduction, and the cost is similar to matte printing-great value for money. Suitable for bags that need to stand out, like snack, toy, or cosmetics packaging.
2. High-End Highlight: UV Printing (Local Brightening, More Premium)
UV printing isn't a separate printing method-it's an additional surface process on top of regular printing (matte/glossy). Simply put, it's like "coating a bright film on part of the pattern" and curing it with UV light, forming a hard, shiny layer.
Features: The local pattern will be bright and raised, with a obvious texture, contrasting with the surrounding regular printing. It highlights key parts like logos or product names, making the bag look more high-end. It's also scratch-resistant, friction-resistant, waterproof, and stain-proof. Suitable for highlighting brand logos and improving packaging texture-like high-end cosmetics bags, gift bags, or brand logo printing.
3. Luxury Texture: Hot Stamping (Gold & Silver) (Metallic Shine, Premium Look)
Hot stamping (gold or silver) works the same way-only the color of the metal foil is different. It uses high temperature and pressure to transfer metal foil (gold or silver) onto the bag's surface, creating metallic patterns or text with a luxurious feel.
Gold Hot Stamping: Has a golden shine, looks elegant and high-end. Perfect for highlighting brand grade-like logos or text on gift bags, high-end food bags, or cosmetics bags. It instantly elevates the packaging's quality.
Silver Hot Stamping: Has a silver shine, simpler and more understated than gold. Suitable for minimalist, cool-style packaging-like skincare, health products, or high-end daily necessities bags. Pair it with matte printing for a perfect texture.
Note: Hot stamping (gold/silver) is usually used for local printing (like logos or small text), not large areas-otherwise, the cost will be higher, and it's easy to have uneven stamping.
4. Special Texture: Aluminum Leaking Printing (Matte Metallic, Elegant & Durable)
Aluminum leaking printing (also called "local aluminum leaking") means printing a layer of metal aluminum film on part of the bag's surface, creating a matte metallic texture-not as shiny as hot stamping or glossy printing, but understated and high-end.
Features: The metallic texture is soft, not glaring, with a slight metallic touch. It has better waterproof and moisture-proof effects, and improves the bag's barrier (to prevent food oxidation, for example). Suitable for high-end food, health products, or cosmetics bags-especially those that need both texture and practicality, like milk powder bags or high-end snack bags.
5. Eye-Catching Style: Laser Printing (Rainbow Reflective, Stand Out)
Laser printing involves printing a layer of laser film on the bag's surface. When light hits it, it shows a rainbow reflective effect-like a rainbow, very cool and eye-catching, with high recognition.
Features: High gloss, rich colors, different reflective effects from different angles-high appearance and attractiveness. It's also waterproof, scratch-resistant, and has a good texture. Suitable for bags that need to be unique and attract young consumers-like snacks, toys, cultural and creative products, gift bags, especially holiday custom bags (Spring Festival, holiday gift boxes).
6. Practical Hidden Style: Internal Printing (No Surface Patterns, Cleaner)
Unlike all the surface processes above, internal printing prints the pattern on the inner side of the bag. The outer surface is solid color (no patterns), looking very clean and minimalist. It avoids pattern wear and fading, and prevents ink from touching the products inside the bag (like food or skincare)-safer.
Features: The outer side is clean and tidy, the inner pattern is clear, safe and environmentally friendly. Suitable for scenes that require high packaging cleanliness and need to avoid ink contact with products-like food bags (especially inner bags that touch food directly), skincare inner bags, or medical product packaging.
