Glass Container

Square Jar

The square glass jar has a four-sided body with flat panels and 90-degree corners, creating a modern, space-efficient container. The flat sides make labeling easy (four usable panels) and allow tight packing on shelves and in shipping cartons with minimal wasted space. Made from food-grade soda-lime glass with plastisol-lined metal screw-top lids that create airtight and vacuum seals.

Square jars are used for spices, jams, sauces, dry goods, candles, and specialty food products.

Got Questions?

frequently asked questions

What is your minimum order quantity (MOQ)?

Lower than you'd expect.

Boxes and insert cards start at 2,500 units. Poly mailers and pouches run 5,000-10,000. Glass and custom bottles sit higher, 50,000-10,000, because mold tooling gets expensive below that.Send us your project details and we'll give you an exact MOQ and quote. No back-and-forth guessing games.

What materials do you manufacture in?

Pretty much everything.

Paper (cardstock, corrugated, chipboard, kraft), plastic (PET, HDPE, PP, bioplastics), glass (jars, bottles, vials, droppers), and metal (tin containers, aluminum). If your product needs packaging, we've probably made something like it before.

We also handle all the finishes that make packaging feel worth keeping: foil stamping, embossing, soft-touch lamination, spot UV, custom die cuts, Pantone matching. The stuff that turns a box into an experience (and gets you those unboxing videos).

If you don't see it listed here, ask anyway. What's on our site is honestly just the starting point.

What does it mean that Paking Duck is a "one-stop shop"?

It means you stop juggling vendors.

Boxes, pouches, bottles, jars, tins, stickers, labels, tissue paper, packing paper, poly mailers, freight. All from us. One point of contact, one production timeline, one invoice. That's the whole pitch.

Most brands piece their packaging together across 4 or 5 suppliers, then spend half their time playing project manager between all of them. We've worked with over 1,000 brands and the ones who consolidate with us always say the same thing: they wish they'd done it sooner. Less coordination, fewer surprises, and one team that's accountable from concept through delivery.

Where are your manufacturing facilities?

Southern China. We run production through our own facilities and dedicated factory partners in Fuzhou, Shenzhen, and Guangzhou, with a team on the ground managing everything.

‍

That means we're not sending specs overseas and hoping for the best. Our people are in the factories overseeing quoting, sampling, and QC in person. We handle DDP shipping straight to your door (or your 3PL), so you don't have to think about freight, customs, or any of that.

‍

The equipment matters too. Our production facilities run printing and finishing machines imported from Germany and Japan. That's how we hit the quality that brands like Madhappy, Tower 28, and Venus et Fleur expect on every run.
