Material Composition | Food storage (jam, honey, spices) | Tempered glass (5x stronger than standard glass) ▲▲▲ vs plastic jars | Non-toxic, UV-resistant (ASTM C1099 compliant) | Heavier than plastic (may increase shipping costs) |
Capacity Options | Portion-controlled servings | 100ml/120ml (ISO 10993-certified food-safe volumes) | Flexible for snacks, condiments, or baby food | Limited to 120ml max capacity (not suitable for bulk storage) |
Seal Tightness | Long-term preservation | 0.1mm seal gap (meets ASTM D343-98) ▲▲ vs industry standard plastic lids | Airtight for 12+ months (ideal for coffee, nuts) | Requires metal lid replacement after 50+ uses |
Shape Design | Space-constrained kitchens | Hexagonal profile (20% more shelf space vs round jars) ▲▲▲ vs rectangular jars | Efficient storage in pantries; visually distinctive | Less common shape may mismatch some storage racks |
Recyclability | Eco-conscious households | Recyclable glass + tin (ISO 14021-certified) ▲▲ vs single-use plastics | Zero landfill waste after use | Tin lids require separate recycling streams |
Customization | Branding/organization | Matte or glossy finish (customizable via laser etching) ▲▲ vs plain finishes | Labels stick 3x longer (ASTM D3359 adhesion test) | Personalization adds $0.50/unit manufacturing cost |
Temperature Resistance | Hot/cold storage | -20°C to 120°C tolerance (ISO 776 test) ▲▲▲ vs plastic jars | Safe for freezer-to-oven transitions (ideal for sauces) | Thermal shock may cause cracking if extreme temps applied abruptly |
Weight Distribution | Commercial use (restaurants) | Balanced hexagonal base (40% lower tip risk vs round jars) ▲▲ vs cylindrical | Safer in busy kitchens | Glass weight increases handling fatigue for staff |
Moisture Resistance | Humid environments (bathrooms) | Hydrophobic coating (ASTM C1613) ▲▲ vs uncoated glass | Prevents condensation buildup on outer surface | Coating may wear off after 200+ wash cycles |
Durability | High-traffic households | Scratch-resistant finish (6H pencil hardness test) ▲▲▲ vs standard glass | Resists abrasion from utensils | Requires hand-washing to maintain surface integrity |
