Mylar Bag Size Calculator
Freeze-dried candy weighs almost nothing but takes up lots of room — order bags by ounces alone and they arrive too small. Pick your candy and bag weight; get the bag size that actually fits, how many to order, and the oxygen absorber cc if you need them.
The sizing table this uses
Capacities are for freeze-dried candy — light, puffed, and irregular — not the dense pre-dry weight. Puffy candy (gummies, marshmallows) fills bags at roughly 25–30% less weight; dense hard candy fits about 30% more.
3″ × 4″ ~0.5 oz (~14 g) 50 cc
4″ × 6″ ~1–1.5 oz (~28–42 g) 100 cc
5″ × 8″ ~2–3 oz (~57–85 g) 100 cc
6″ × 9″ quart ~3–4 oz (~85–113 g) 100–200 cc
8″ × 12″ ~7–9 oz (~200–255 g) 300 cc
absorber rule of thumb: ~100 cc per quart of bag volume
bags needed = batch weight after drying ÷ candy per bag
Weight after drying comes from your candy's water content — candy loses far less weight than fruit does. The yield calculator breaks that down per candy type.
Mylar bag & absorber FAQ
What size mylar bag do I need for freeze-dried candy?
Size by candy type, not just ounces — freeze-dried candy is bulky for its weight. Rule of thumb: 3×4″ holds about half an ounce, 4×6″ about 1–1.5 oz, 5×8″ about 2–3 oz, and a 6×9″ (quart) bag about 3–4 oz. For puffy candy like gummies and marshmallows, drop one capacity step.
What size oxygen absorber goes in a quart mylar bag?
Roughly 100cc per quart of bag volume is the standard rule: 50–100cc for small 3×4″ and 4×6″ bags, 100–200cc for a 6×9″ quart bag, 300–500cc for a gallon. Oversizing is harmless; undersizing defeats the point.
Does freeze-dried candy that sells quickly need oxygen absorbers?
Usually not. Sugar doesn't oxidize the way fats do, so candy eaten within weeks or months keeps fine in a well heat-sealed bag alone. The real enemy is moisture — freeze-dried candy turns chewy if the seal leaks. Save the ~$0.05–0.10 per bag unless you're selling a long-term storage product.
How thick should mylar bags be for candy?
3.5–5 mil is the retail norm — survives market tables and shipping, seals easily with an impulse sealer. 7 mil+ "25-year storage" bags are overkill for candy and cost noticeably more per unit.
