Why Choose This Product?
Center seal bags are the workhorse of Singapore’s automated food packaging lines. Bakeries use them for bread and pastries; manufacturers use them for loose products that need quick, consistent packaging. The centre-back seal creates a clean front face for branding while the pillow shape provides good product protection. We offer pre-formed bags (ready to fill) or printed film rolls for form-fill-seal machines, whichever suits your production line.
Common Applications in Singapore
- 🍞 Bakeries — bread loaves, buns, curry puffs, traditional kueh
- 🍿 Snack factories — keropok, murukku, cracker packaging
- 🥬 Fresh produce — vegetables, salad mixes at wet markets
- 🏭 Manufacturing — hardware components, pharmaceutical strips
- 🛒 Retail — loose products at self-service counters
Frequently Asked Questions
What’s the difference between center seal and 3 side seal?
Center seal bags are made from tubular film with a single seal down the centre back. 3 side seal bags have three sealed edges. Centre seal is better for automated line filling.
Can I get these on a roll for VFFS machines?
Yes, printed film rolls for vertical form fill seal machines are our most common format for center seal bags.
Are the seals leak-proof?
Standard seals are secure for dry products. For liquids, we recommend laminated films with stronger seal layers.
What printing options are available?
Full-bleed rotogravure or flexographic printing. Up to 10 colours.
What is the typical lead time?
3-4 weeks for printed film rolls. 2-3 weeks for pre-formed bags.
