Choosing the right PET jar size isn’t just about how much product it holds — it’s about neck diameter, cap compatibility, shelf presentation, and cost per unit at scale. Most FMCG buyers searching for “PET jar sizes” or “PET jar price list” end up comparing scattered supplier quotes with no consistent reference point. This guide fixes that: a single, clear sizing chart, a transparent starting price range, and a real buying scenario showing how the right size choice affects cost and shelf appeal.
Why PET Jar Size Selection Matters
PET jar sizing is described two ways: neck size (measured in mm, referring to the cap opening) and capacity (measured in ml, referring to how much product fits inside). Two jars can share the same neck size but hold very different volumes depending on body height and shape. Getting this wrong after placing a bulk order is expensive — MOQs in this industry typically start at 5,000 pieces, so sizing mistakes aren’t cheap fixes.
PET Jar Size & Capacity Chart
| Neck Size | Typical Capacity Range | Common Use Case |
|---|---|---|
| 38mm | 100ml – 250ml | Spices, seasoning, sample packs |
| 53mm | 250ml – 500ml | Dry fruits, small snacks, cosmetic creams |
| 63mm | 400ml – 750ml | Namkeen, cookies, pulses |
| 73mm | 600ml – 1000ml | Ghee, edible oil, larger snack packs |
| 83mm | 800ml – 1500ml | Bulk dry fruits, rice, wide-mouth storage |
| 96mm | 1200ml – 2000ml | Bulk confectionery, large-format retail |
| 120mm | 2000ml – 3000ml+ | Institutional/bulk food service packaging |
Note: actual capacity varies by jar shape (round, square, oval) and wall thickness — always confirm with a sample before finalizing a bulk order.
Public Pricing Reference (Approximate, Ex-Factory)
Pricing depends on neck size, cap type, resin thickness, and order volume, but as a starting reference:
- Standard screw-cap PET jars: ₹10–13 per piece approx.
- Jars with premium metal-finish caps (gold/silver): ₹14–22 per piece approx.
- Flip-top / specialty cap jars: ₹15–20 per piece approx.
- Minimum Order Quantity (MOQ): 5,000 pieces per SKU (varies by product/size)
Prices are indicative and move with resin costs, so always request a current quote for exact numbers — but this range gives buyers a realistic budgeting baseline before reaching out.
Case Study: Right-Sizing Packaging for a Dry Fruit & Namkeen Brand
The problem: A growing dry fruit and namkeen brand was using a single 500ml jar size across its entire product range — pistachios, roasted makhana, and mixed namkeen — to simplify ordering. The result was inconsistent: premium dry fruits looked under-filled in the jar, while namkeen packs felt cramped, hurting shelf appeal and increasing customer complaints about “half-empty” packaging.
The fix: After a sizing consultation, the brand switched to a tiered approach — 63mm/400ml jars for namkeen and snacks, 53mm/300ml jars for premium dry fruits with a gold metal cap for a higher-value look, and 83mm/1000ml jars for bulk institutional orders.
The result: Fill-ratio complaints dropped, the premium dry fruit line saw better shelf pull-through due to the upgraded metal cap presentation, and the brand reduced per-unit packaging cost on the bulk SKU by ordering the right jar instead of over-packing a smaller one. The brand now reorders three distinct SKUs instead of guessing with one, and repeat orders have stayed consistent for over two years.
Takeaway: Matching jar size to product type — not defaulting to “one size fits all” — directly affects both perceived product value and packaging cost efficiency.
Frequently Asked Questions
What is the most common PET jar neck size for dry fruits and spices?
53mm and 63mm neck sizes are the most widely used for dry fruits, spices, and namkeen, typically holding 250ml–750ml depending on jar height and shape.
What is the minimum order quantity (MOQ) for PET jars?
MOQ is generally 5,000 pieces per size/SKU. It can vary slightly based on customization requirements like color, cap type, or branding.
Can I get a sample before placing a bulk order?
Yes — most manufacturers, including Radhika Polymers, provide samples so you can evaluate jar quality, shape, and cap fit before committing to a bulk purchase.
Do larger jars cost proportionally more per ml than smaller ones?
Not always. Larger jars often have a lower cost-per-ml due to production efficiency, even though the per-piece price is higher — worth calculating both metrics before deciding.
Are custom sizes or shapes available beyond the standard chart?
Yes, custom shapes, colors, and cap types are typically available on request, though custom molds may involve longer lead times and higher MOQs than standard sizes.
How do I know if a metal-cap or plastic-cap jar is right for my product?
Metal-finish caps suit premium/gifting positioning (dry fruits, ghee), while plastic screw caps are more cost-effective for everyday snack and spice packaging at scale.
