If you manufacture red envelopes, greeting cards, wedding invitations, or stationery gifts, you already know one thing:
Presentation is everything.
These products are highly visual. Customers judge them within seconds. If the surface is scratched, the corners are bent, or the plastic sleeve looks uneven, the perceived value drops immediately.
And yet, many factories still rely on manual labor or basic vertical machines for red envelope packaging.
Here’s what usually happens:
-
Workers leave fingerprints on glossy finishes
-
Foil stamping gets scratched
-
Embossed surfaces get compressed
-
OPP film builds static and sticks together
-
Packaging speed can’t keep up during holiday peaks
So the real question is:
How do you automate red envelope packaging without damaging delicate finishes like hot stamping or embossing?
This is exactly why the UBL T type bagging machine was developed.
It’s not just another paper product packaging machine. It’s specifically engineered for thin, lightweight, high-value printed materials.
Why a T Type Bagging Machine Is Different from Vertical Baggers
Most traditional bagging machines use a vertical drop structure. That works fine for rigid or heavier items.
But red envelopes are thin and lightweight.
When they drop vertically:
-
They flip
-
They tilt
-
They misalign
-
They sometimes jam
The UBL T type bagging machine uses a horizontal feeding structure — also known as a T-shape architecture.
Instead of falling into the bag, the red envelope is pushed forward on a stable horizontal track. That means:
-
No flipping
-
No corner damage
-
No surface friction from falling
-
No random misalignment
For premium paper product packaging, this design makes a huge difference.
Gentle Handling for Premium Print Finishes
High-end red envelopes often include:
-
Gold foil stamping
-
Embossed patterns
-
UV coating
-
Textured paper
These details cannot tolerate mechanical scraping.
The UBL red envelope bagging machine uses a vacuum suction system to open the bag. There is no aggressive mechanical gripping.
This non-contact bag opening technology:
-
Protects foil surfaces
-
Prevents scratching
-
Keeps embossing intact
-
Maintains surface gloss
If you’re in premium stationery manufacturing, this level of protection is critical.
Anti-Static System: Solving the OPP Film Problem
If you’ve ever run OPP film, you know the headache.
Static electricity builds up fast. Bags stick together. Multiple sheets feed at once. Machines stop. Operators get frustrated.
The UBL T type bagging machine integrates a professional anti-static elimination system.
That means:
-
Smooth single-sheet feeding
-
No film sticking
-
Fewer stoppages
-
More stable production
For high-volume red envelope packaging, this stability translates directly into higher efficiency.

Special Features Designed for the Paper Industry
Automatic Hang Hole Punching
Retail packaging often requires a hanging display.
The UBL red envelope bagging machine can integrate:
-
Euro hole (airplane hole)
-
Round hole
So after bagging, the product is ready for direct retail shelving.
No secondary processing needed.
Clean and Precise Sealing
The machine supports:
-
Back sealing
-
Three-side sealing
The seal line is thin, consistent, and strong — without interfering with printed designs on the back of the red envelope.
Uniform sealing also improves shelf appearance and brand perception.
Single or Multi-Pack Options
Depending on market needs, the T type bagging machine supports:
-
Single-piece bagging
-
Automatic counting and stacking (5 or 10 pieces per pack)
Perfect for gift sets or bulk stationery bundles.
Reliability You Can Count On
At UBL, performance isn’t just about speed. It’s about stability.
Every T type bagging machine undergoes:
168 hours of continuous run testing before shipment.
This ensures high MTBF (Mean Time Between Failures) and long-term reliability.
When peak season hits — Lunar New Year, wedding season, holiday sales — your production line keeps running.
24/7 if needed.
Why Automation Elevates Brand Value
Red envelope packaging is not just about adding a plastic sleeve.
It’s about:
-
Protecting craftsmanship
-
Enhancing perceived value
-
Improving retail presentation
-
Stabilizing production output
-
Reducing labor dependency
A professional paper product packaging machine turns packaging into a competitive advantage.
And the UBL T type bagging machine is built specifically for that mission.
