What Are 7 Mil Mylar Bags?
Film thickness in mylar packaging is measured in mil, and 7 mil sits on the heavier end of the range, giving the bag noticeably more resistance to punctures, tears and general wear than thinner options. Long-term storage businesses, bulk food producers and any operation handling product in rougher conditions rely on this gauge because standard-thickness film can develop small holes or weak points under repeated handling, stacking or shipping stress. The advantage here is durability under pressure, both literally in terms of physical handling and in terms of maintaining a barrier seal over extended storage periods.
Why Choose 7 Mil Mylar Bags?
A real issue with thinner film is that it can develop pinholes or small tears from rough handling, stacking, or contact with sharp edges during storage or transit, and even a tiny puncture undermines the whole barrier. A thicker 7 mil gauge solves this by giving the bag genuine physical resistance to the kind of wear that would compromise a standard-thickness pouch. It's the gauge we point buyers toward most within our Mylar Pouches range when durability is the priority.
Key Benefits of 7 Mil Mylar Bags
Product protection is significantly stronger at this thickness, with better puncture and tear resistance than standard film gauges. Brand visibility still works through full-colour print, though this format tends to prioritise function for buyers dealing with rougher storage or shipping conditions. Customer experience benefits from a bag that stays intact and functional even after repeated handling. Business advantages suit long-term storage, bulk shipping and any use case where standard film has previously failed.
Customisation Options
Sizing and closure options remain flexible at this thickness, with heat seal commonly chosen for maximum seam strength. Gusset styles can be adjusted to handle bulkier or heavier fill weights that this gauge is built to support.
Printing & Finishing Choices
Full-colour print is available, though many buyers choosing this thickness prioritise film performance over decorative finishing. A simple matte finish is common where function outweighs shelf presentation.
- Suitable Uses: This gauge suits long-term storage operations, bulk food producers, and any business shipping or storing product in conditions likely to stress thinner packaging, often ordered alongside our Custom Shipping Boxes for outer transit protection.
Why Choose Unique Custom Boxes?
Quality checks specifically test seam strength and puncture resistance at this thickness before dispatch, and competitive pricing keeps heavier-gauge film accessible even for smaller orders. Wholesale capability and UK-wide delivery in 8 to 12 days support businesses ordering this gauge regularly.
