Do you offer next working day delivery?
Yes—orders placed before the daily 15:00 cut-off qualify for next working day UK delivery. Weekends and bank holidays are excluded.
Are self-seal bags food-safe?
Yes—self-seal bags in this category are suitable for direct food contact. Check individual product pages for compliance details.
Are self-seal bags airtight or leakproof?
They are resealable and leak-resistant for dry goods, but not designed for liquids. Keep liquids upright or choose an alternative packaging solution.
Can I vacuum-seal these bags?
No—self-seal grip bags are not designed for air extraction. For this purpose, use dedicated vacuum bags.
Do you stock perforated self-seal bags?
Self-seal bags are typically non-perforated to keep contents sealed. For airflow, choose perforated polythene bags instead.
Are they freezer-safe or microwave-safe?
Some lines are freezer-suitable—check each product’s temperature guidance. Self-seal bags are not recommended for microwave use.

We stock a wide range, from small parts bags to larger storage sizes, in light, medium and heavy gauges. Exact dimensions and micron/gauge details are listed on each product page.
