Plastic Bag Types Guide: Vest Bags, Hole Punch Bags & Flat Bags
Faced with countless plastic bag options, many buyers ask the same question: what's the difference between vest bags, hole punch bags, and flat bags? This guide compares these three most common types by structure, carry method, opening design, and ideal applications.
Vest Bags (T-Shirt Bags / Carrier Bags)
Structure
Vest bags feature integrated T-shaped carry handles, sealed bottom, and top opening between handles. The one-piece molded design ensures consistent structural strength during high-volume production.
Best For
- Supermarket and market checkout bags
- Restaurant and food takeaway
- Produce and fresh food packaging
- Retail shopping bags
- General merchandise
Materials
Primarily HDPE (rigid, strong, cost-effective) or LDPE (soft, transparent, premium feel).
Hole Punch Bags (Die-Cut Handle Bags)
Structure
A flat bag with a circular or oval hole punched near the top for carrying. The flat, uninterrupted surface maximizes print area. Holes can also allow bags to hang on display hooks.
Best For
- Brand store shopping bags
- Fashion retail packaging
- Gift and souvenir packaging
- Trade show and exhibition materials
- Display rack product packaging
Materials
HDPE, LDPE, or OPP depending on transparency and print quality requirements.
Flat Bags (Open-Top Bags)
Structure
The simplest design: a rectangular bag with sealed bottom and sides, open at the top. No carry handles. Designed for filling from above and sealing with heat sealers, twist ties, or tape.
Best For
- Food portioning (snacks, candy, flour, frozen food)
- Garment inner bags
- Pharmaceutical packaging
- Industrial parts sorting and dust protection
- Agricultural seed and fertilizer bags
Materials
Primarily LDPE for transparency and sealing compatibility. HDPE for strength in industrial applications.
