FAQs

What certifications does this bag carry for ice contact?

The film is food-grade LDPE — the appropriate base material for direct ice contact. Food-contact declarations and migration test reports from an accredited laboratory are issued per structure against an order. If your customer or regulatory authority requires documented food-contact compliance, tell us your market and we will arrange the testing and provide the paperwork with the first production order.

How does the user fill the bag correctly?

The bag is filled by placing it under a tap or filling each compartment individually with water, then sealing and placing it flat in the freezer. When the ice is frozen, the bag is twisted to release cubes from their compartments, then the top is opened. The 30-micron LDPE is thin enough that the twist-and-release technique works without force; a heavier gauge would not release as cleanly.

Can you supply these as compostable bags?

Not as this product. A self-seal ice cube bag is plain food-grade LDPE, and we do not label it compostable or biodegradable because it holds no EN 13432, ASTM D6400 or BPI certificate. We also will not supply degradant additives, which are restricted in the EU and would in any case leave you with a film that fragments rather than composts. If your market genuinely requires a certified compostable ice bag we will quote a certified compostable film as a separate structure, with the certificate supplied against the order.

Can I order a plain bag first and add printing later?

Yes. Plain clear bags can be with you within 10 days for a trial. Custom-printed bags need print-cylinder or plate preparation first, so allow additional time for artwork approval and proof sign-off before production. Mixing plain and printed bags in the same shipment is possible.

What is the realistic shelf life of the frozen ice in the bag?

Ice in a sealed LDPE bag in a frost-free freezer does not evaporate noticeably and does not absorb odours from adjacent items, which means the bag can stay in the freezer until needed. Without a sealed top closure, ice will slowly sublimate. Seal the bag after filling and the ice quality holds for a standard domestic or commercial freezer cycle.

FAQs

How do I get a quotation?

Send the flat size in mm, the structure or simply what goes inside and how long it has to keep, the number of print colours or the artwork itself, and the quantity and destination port. We come back with a costed offer, a lead time and a recommended specification. If part of the brief is still open we will quote the options side by side.

What certifications do your products carry?

Our products carry the following certifications:

  • ISO 9001:2015 – Quality Management System
  • FDA Compliant – For food-contact packaging
  • EN 13432 – For compostable products

What sizes and thicknesses can you produce?

We manufacture across the full commercial range:

  • Thickness: 6 microns to 200 microns depending on product type
  • Width: 80mm to 1,600mm
  • Length / capacity: fully customizable per specification

Send us your target dimensions and we will confirm feasibility and tooling cost (if any) within 24 hours.

Can you produce with custom printing and branding?

Yes. We offer in-house printing across multiple technologies:

  • Gravure printing: up to 10-color gravure, registration accuracy < 0.2mm
  • Flexographic printing: up to 6-color flexo
  • Digital printing: available for low-volume, multi-design runs

We accept artwork in Adobe Illustrator (.AI), PDF (vector), EPS, or CDR formats. Color matching to Pantone (PMS) codes is standard.

What are your standard production lead times?

Lead times after order confirmation and approved pre-production sample (PPS):

  • Standard products (no custom printing): 15–20 working days
  • Custom printed products: 20–25 working days
  • Large-volume orders (multiple containers): 25–35 working days

Free standard samples typically ship within 5–7 working days; pre-production samples within 5–10 working days after artwork sign-off.

How is quality control managed?

We operate a four-stage quality control protocol with full batch traceability:

  • Incoming: melt flow, density, and contamination testing on every resin batch
  • In-process: real-time gauge, registration, and seal integrity monitoring
  • Finished goods: tensile, elongation, dart impact, and heat seal testing per batch
  • Pre-shipment: AQL 1.5 sampling inspection with full compliance documentation

Production sites are certified to ISO 9001, ISO 14001, and BRC Global Standard for Packaging.
