Carton Forming Bottom Sealing Machine | Case Erector Equipment
SunAura carton forming bottom sealing machines automatically form flat corrugated blanks into three-dimensional boxes and seal the bottom. Available with tape, hot melt adhesive, or steel nail sealing. Models range from NTCF-400 (8-12 BPM, nail) to MSCE-1000 (15-20 BPM, tape) and HMGCE-500 (8-12 BPM, hot melt). All models are CE certified with 304 stainless steel construction.
Product Description
SunAura offers a complete range of carton forming bottom sealing machines with three sealing technologies: tape sealing, hot melt adhesive sealing, and steel nail sealing. Each technology has specific advantages for different applications. Tape sealing is cost-effective and versatile, hot melt adhesive provides permanent tamper-evident bonds for heavy and export packaging, and steel nail sealing offers maximum bottom strength for heavy industrial products.
All machines automatically receive flat corrugated carton blanks from a magazine, form them into three-dimensional boxes, and seal the bottom. This eliminates manual carton erection labor and ensures consistent box dimensions for downstream filling and top sealing operations. The machines handle carton sizes from 200x150x100mm to 800x600x600mm across the model range.

Frequently Asked Questions
Which sealing method should I choose?
Tape sealing is versatile and cost-effective for general packaging. Hot melt adhesive provides permanent, tamper-evident bonds ideal for heavy products, frozen goods, and export packaging. Steel nail sealing offers maximum bottom strength for heavy industrial products where tape and glue may be insufficient.
What is the speed range of the machines?
Speeds range from 8-12 cartons/min (NTCF-400 nail sealer and HMGCE-500 hot melt) to 15-20 cartons/min (MSCE-1000 medium speed tape sealer). The CE-600 and CE-800 offer 10-15 and 12-18 cartons/min respectively for tape sealing applications.
What carton sizes can the machines handle?
Across the model range, machines handle cartons from 200x150x100mm (NTCF-400 minimum) to 800x600x600mm (CE-800 maximum). Each model has specific size ranges, so select the model that covers your carton dimensions.
Are the machines suitable for food packaging?
Yes, all machines feature 304 stainless steel construction meeting FDA, CE, and international food safety standards. Hot melt adhesive used in HMGCE-500 is food-grade compliant for indirect food contact packaging.
Can the machines be integrated into existing packaging lines?
Yes, all models feature standard conveyor height and compact designs for easy integration with carton fillers, top sealers, strapping machines, and other packaging line equipment.
What are the power requirements?
All machines operate on 220V/380V, 50/60Hz power supply, customizable for different regional standards. Motor power ranges from 0.5KW (NTCF-400) to 2.5KW (HMGCE-500 including glue melting system).
How do I select the right model for my application?
Consider your required speed, carton size range, product weight, and sealing method preference. For light products, tape sealing (CE-600/CE-800) is sufficient. For heavy products, nail sealing (NTCF-400) is recommended. For frozen or export packaging, hot melt (HMGCE-500) is ideal. For maximum speed, MSCE-1000 is the best choice.
