Choosing the Right Mylar Bag Size
When it comes to packaging your products, size matters. The right mylar bag protects your product, looks professional on the shelf, and gives customers the right amount. At CaliPack Pro, we offer four core sizes — here’s how to choose.
3.5g (⅛ oz) — 85 × 130mm
Best for: Samples, trial sizes, single portions, and premium individual servings.
The 3.5g bag is our most popular size for brands launching new products. It’s compact enough for counter displays and vending, yet large enough to hold a meaningful portion. Food-grade PET + aluminium laminate keeps contents fresh and protected from light, moisture, and odour.
Popular use cases: Coffee samples, loose leaf tea portions, spice sachets, supplement servings, artisan snacks.
Price: From £0.25 per unit with bulk discounts up to 30% at 500+ units.
7g (¼ oz) — 100 × 150mm
Best for: Retail-ready packaging, gift sets, and standard portions.
The 7g bag is the sweet spot for most retail brands. It’s large enough to feel substantial in the customer’s hand while keeping costs manageable. The wider dimensions (100mm) give your branding more room to shine.
Popular use cases: Retail coffee bags, herbal blends, pet treats, confectionery, cosmetic samples.
Price: From £0.30 per unit.
14g (½ oz) — 120 × 180mm
Best for: Bulk retail, multi-serving portions, and premium products.
The 14g bag offers a generous canvas for your brand artwork. The larger surface area makes holographic and prism finishes especially eye-catching on shelves. Ideal for products where a larger quantity adds perceived value.
Popular use cases: Premium coffee, bulk spices, supplement pouches, dried fruit, artisan goods.
Price: From £0.35 per unit.
28g (1 oz) — 150 × 230mm
Best for: Wholesale, trade quantities, and value packs.
Our largest standard bag — the 28g is a workhorse for wholesale distribution and bulk packaging. The 150 × 230mm dimensions provide maximum shelf impact and brand real estate.
Popular use cases: Wholesale coffee, bulk tea blends, large supplement bags, pet food packaging.
Price: From £0.40 per unit.
