FAQ
Q: Is the 110ml flask bottle suitable for hot-filling beverages?
A: This bottle is designed for room temperature or cold-fill liquids. If your process requires hot-fill (up to 70℃, we recommend a pre-heating stage to avoid thermal stress. For carbonated beverages, please consult our technical team for pressure-rated alternatives.
Q: What type of cap is best for sealing high-proof spirits in this flask?
A: We recommend Aluminum ROPP caps with a chemical-resistant liner or Tamper-Evident Plastic Screw Caps. These provide the best barrier against ethanol vapor transmission and ensure product integrity during shipping.
Q: Can I customize the embossing (logo) on the flat side of the bottle?
A: Yes. The flat front and back surfaces are ideal for custom embossing. New mold development for custom logos typically takes 15-20 days, and we provide 3D technical drawings for approval before production.
Q: How is the breakage rate managed for international wholesale orders?
A: We utilize a "Double-Protection" packaging system: bottles are first packed in cell-partitioned cartons, then palletized with edge protectors and high-tension shrink wrap. This maintains our global breakage rate at under 0.5%.
