Choosing the Right Plastic Jar: A Buyer’s Guide for Small Businesses, Crafters, and Cannabis Brands

Not all plastic jars are created equal. Whether you're packaging edibles, bath salts, concentrates, or craft items, the right jar can make all the difference in presentation, compliance, and customer satisfaction. Here's how to choose the best option for your business.

1. Material Matters: PET vs. Glass vs. Polypropylene

  • PET (Polyethylene Terephthalate): Lightweight, crystal-clear, shatter-resistant. Great for visual products and shelf appeal.
  • Polypropylene: More flexible and heat-tolerant, often used for creams or topicals.
  • Glass: Heavy, breakable, but premium-feeling. Often overkill unless targeting luxury markets.

Pack Supply stocks high-clarity PET jars with smooth and ribbed lid options.

2. Know Your Sizes: One Ounce Does Not Fit All

Jars range from 1 oz to 16 oz, each with specific use cases:

  • 1 oz: Samples, topicals, lip balms
  • 4 oz: Concentrates, gummies, bath soaks
  • 8 oz+: Bulk flower, candles, craft goods

3. Lid Styles & Why They Matter

The lid is your customer's first point of contact. Choose based on security, compliance, and aesthetic:

  • Child-Resistant: Required for most cannabis products
  • Smooth-Sided: Sleek look, easy to label
  • Ribbed: Easy grip, classic apothecary feel
  • Dome: More elegant and upscale

4. Labeling & Branding Tips

Labels must fit cleanly, resist peeling, and stay legible. Quick tips:

  • Use a matte finish for soft-touch feel
  • Match label size to visible area (minus lid curve)
  • Consider tamper-evident seals or shrink bands for safety

5. Domestic vs. Overseas: Why Buy from a U.S.-Based Supplier

Importing jars seems cheaper until it isn’t. With Pack Supply, you get:

  • No import delays or customs issues
  • Faster lead times on repeat orders
  • Access to lower MOQ custom runs
