Freezer Bags in Portsmouth, NH
Portsmouth is one of New England's most beloved small cities — a beautifully preserved colonial seaport with one of America's most vibrant restaurant and food scenes per capita, a boutique retail community on Market Street, a thriving arts community, and a tech economy anchored by Liberty Mutual and defense contractors. The city's extraordinary food culture, premium retail environment, and growing startup community make Portsmouth one of the most commercially sophisticated small cities in the Northeast. My Custom Boxes serves Portsmouth's premium and food-forward business community.

Why Choose Our Freezer Bags
Custom Freezer Bags | Frozen Food Packaging for Meat, Produce & Specialty Brands
Freezer bags are engineered for the specific mechanical and barrier demands of frozen food packaging — film materials that remain flexible and impact-resistant at subzero temperatures where standard polyethylene becomes brittle, barrier constructions that prevent freezer burn (moisture loss from the frozen food surface through vapor pressure differential), and seal integrity that maintains at -20°F/-29°C freezer temperatures through the distribution and home storage chain.
Freezer Packaging Applications
- Frozen Fruit and Vegetables: Moisture-barrier freezer bags for IQF (individually quick frozen) produce retail
- Frozen Meat and Seafood: Heavy-gauge freezer bags with oxygen barrier for frozen protein retail
- Frozen Meal Components: Portioned freezer bags for meal kit and prepared food meal components
- Ice Cream and Frozen Desserts: Moisture-barrier bags for frozen dessert products requiring temperature stability
- Custom Frozen Food Brands: Premium printed freezer bags for specialty frozen food DTC and retail brands
Freezer Burn: What It Is and How Packaging Prevents It
Freezer burn is the dehydration and oxidation of frozen food surfaces — ice crystals sublimate from the food surface into the air space within the package, causing the characteristic dry, discolored, crystalline texture that makes frozen food unpalatable. Packaging prevents freezer burn by minimizing the air space around the frozen product (tight-fit packaging or vacuum sealing) and by using moisture-barrier film that reduces vapor pressure-driven ice crystal migration through the film walls.
Film Selection for Frozen Food Performance
Standard LDPE becomes brittle and impact-vulnerable at freezer temperatures — a significant packaging failure risk for bags handled in frozen distribution environments. LLDPE (linear low-density polyethylene) maintains flexibility and impact resistance at -20°F/-29°C through its branched polymer structure that prevents the crystal ordering that embrittles LDPE at low temperatures. For meat and seafood with sharp bone and edge exposure, nylon/PE (PA/PE) laminate provides the puncture resistance required to prevent bag failure from internal product pressure at freezer temperatures.
Vacuum Sealing for Maximum Freezer Life
Vacuum-sealed freezer bags eliminate the air space where ice crystal sublimation (freezer burn) originates. By removing atmospheric air and creating direct film-to-food contact, vacuum sealing minimizes the vapor pressure differential that drives moisture migration from food surfaces. The result is dramatically extended freezer life — vacuum-sealed fresh beef maintains quality for 12+ months at 0°F/-18°C versus 4–6 months for conventionally sealed bags — a compelling value proposition for specialty frozen food brands competing on product quality.

Freezer Bags in Portsmouth — FAQs
What film is best for freezer bags?
LLDPE is the standard for frozen food bags — it maintains flexibility and impact resistance at freezer temperatures where standard LDPE becomes brittle. Nylon/PE (PA/PE) laminate provides enhanced puncture resistance for meat and seafood with sharp bones or edges. For maximum barrier against freezer burn, PET/foil/PE or metallized PET/PE constructions significantly reduce moisture vapor transmission rates.
What causes freezer burn and how does packaging prevent it?
Freezer burn occurs when ice on the food surface sublimes (converts directly to vapor) into the air space within the package. This dehydrates the food surface and, over time, oxidizes the exposed tissue. Prevention: minimize air space (vacuum sealing eliminates it), use moisture-barrier film (reduces vapor transmission through package walls), and store at consistent temperature (temperature fluctuation accelerates sublimation).
Can freezer bags be printed?
Yes. Freezer bags are printed using flexographic or rotogravure printing on the outer film surface. The printing must use inks that maintain adhesion and color stability at freezer temperatures — standard inks may crack or peel when cycled between freezer and ambient temperatures. We use cold-temperature-stable ink formulations for all frozen food packaging printing applications.
Are freezer bags food-safe?
Yes. Our freezer bags use FDA 21 CFR compliant food-contact materials throughout — LLDPE and nylon/PE constructions with food-safe adhesives and inks. For direct food contact in frozen applications, we specify materials verified for food safety at the temperatures encountered in the full cold chain from -20°F production freezing through -0°F retail and home storage.
