Are you looking for a packaging solution that both retains temperature effectively and builds brand identity for your bubble tea shop? Hop Phat Sewing proudly introduces the Sweet Heart insulated bag for bubble tea — specially designed for beverage shop owners, café chains, and professional delivery services. Featuring a fresh pastel matcha green color and the message “WISH YOU CAN HAVE A GOOD MOOD,” this product not only protects drinks but also spreads positive energy to every customer.
Aesthetic Design – Impressive at First Glance
In today’s fiercely competitive bubble tea market, packaging is the face of your brand. The Sweet Heart bag features a modern design with a soft matcha green tone — a color shade loved by young consumers for its freshness, approachability, and alignment with the healthy lifestyle trend.
Key aesthetic highlights:
- “SWEET HEART” logo printed prominently on an elegant pastel green background
- Slogan “WISH YOU CAN HAVE A GOOD MOOD” creates positive emotions
- Soft beige/cream canvas handles — comfortable and pleasant to hold
- Unique sun-shaped metal button at the handle attachment point — a small detail that makes a big difference
Ms. Huong Mai, owner of “Trà Sữa Yêu Đời” (Happy Life Bubble Tea) shared: “My customers love this bag. Many even take photos for Instagram because it’s so pretty. That’s the best free advertising!”

Premium Materials – Invest Once, Use for a Long Time
Hop Phat Sewing understands that product quality is the foundation for building customer trust. Therefore, the Sweet Heart insulated bag is crafted from the finest materials.
Durable Outer Fabric Layer
Laminated non-woven fabric or PVC-coated Polyester forms the protective shell of the bag. No more worrying about:
- Sudden rain soaking the bag during delivery
- Difficult-to-clean stains after repeated use
- The bag tearing or breaking after just a few weeks
The glossy surface is not only visually appealing but also extremely easy to clean — just wipe with a damp cloth and it looks brand new!
Smart Thermal Inner Lining
This is the “heart” of the bag. A reflective aluminum film combined with 3–5mm thick EPE foam creates a highly effective multi-layer insulation system.
The aluminum film reflects heat, preventing temperature exchange with the outside environment. The EPE foam is soft yet firm — both retaining heat and providing shock protection for drink cups. The result? Bubble tea stays warm for 2–3 hours, cold drinks remain chilled for 3–4 hours — perfect timing for any delivery order!
Canvas Handles – Sturdy and Comfortable
It’s no coincidence that Hop Phat Sewing chose cotton canvas for the handles. At 2.5–3cm thick, the handles:
- Bear weight well — safe even when carrying 4 large-size bubble tea cups
- Soft and gentle on the hands during long carries
- Durable over time — no sagging or stretching
Mr. Tuan, a shipper for a well-known bubble tea chain, shared: “I deliver all day with this bag. The handles are very comfortable — no shoulder pain like other bags. The bag also keeps drinks at temperature well, so customers have no complaints.”

Optimal Dimensions – Just Right for Every Need
The bag is designed with dimensions of 25cm × 15cm × 30cm — a carefully calculated figure. Not too bulky, not too small. Just right!
Actual capacity:
| Drink Type | Quantity That Fits |
|---|---|
| Medium bubble tea cup (500ml) | 3–4 cups |
| Large bubble tea cup (700ml) | 2–3 cups |
| XL bubble tea cup (1000ml) | 2 cups |
| With topping box / pastry | Possible |
The rigid cardboard-reinforced square base keeps the bag standing upright like a box. You can stack multiple bags when transporting in bulk without worrying about spilling or tipping.
Thermal Performance – Technology in Every Detail
The top concern customers have when buying takeaway bubble tea is: “Will the drink still taste good when I get home?” The Sweet Heart bag answers that question with advanced insulation technology.
How it works:
- Aluminum film creates a heat barrier, reflecting 90% of temperature
- EPE foam provides insulation, slowing the rate of heat transfer
- Folded top closure with Velcro seal — prevents cold/hot air from entering
Real-world test results:
Initial temperature: 65°C (hot bubble tea) Ambient temperature: 28°C
⏰ After 1 hour: 58–60°C — Still very warm ⏰ After 2 hours: 50–52°C — Moderately warm, best to drink ⏰ After 3 hours: 42–45°C — Lightly warm, still usable
Compared to regular kraft paper bags which retain heat for only 30 minutes, the Sweet Heart bag is 6 times more effective!
Marketing Tool – A Smart Investment for Your Brand
Think of the insulated bag not just as a cost, but as a smart marketing investment. Every bag is a mobile billboard advertising your brand everywhere.
Specific branding benefits:
- Customers carry the bag to work and school — your brand appears in many locations
- Beautiful design encourages customers to keep and reuse the bag
- Friends and colleagues who see the attractive bag will ask about your shop
- Long-term marketing costs are much lower than online advertising
Ms. Thanh Nga, a marketing expert, shared: “A beautiful bag can generate hundreds of brand touchpoints over 6–12 months. Compared to the cost of running Facebook Ads, this is an extremely effective investment in terms of ROI!”

Flexible Customization – Your Brand, Your Style
Hop Phat Sewing understands that every brand has its own identity. Therefore, we support full design customization on request:
- Shop logo printing: Flexible positioning and sizing
- Color changes: Choose colors that match your brand identity

- Size adjustments: Tailored to specific usage needs

Eco-Friendly – The Trend of the Future
Today’s younger customers (Gen Z, Millennials) are especially concerned about environmental issues and prefer brands that take responsibility for nature.
The Sweet Heart bag can be reused dozens of times, significantly reducing plastic waste:
- Replaces hundreds of single-use plastic bags
- Reduces pressure on landfills and oceans
