Choosing the Right Bottle Supplier

When bringing a bottled product to market, the type of bottle you choose and the bottle supplier you partner with can have a significant impact on your bottom line. It’s important to work through your list of requirements and specifications to identify the right design for your product — as well as the supplier that best meets your production needs.

Step 1: Pinpoint Your Bottle Design

You can get a good sense of the direction you’d like to take your packaging bottle by examining the types of bottles used by your competitors. Ultimately, the right bottle design necessitates considering several factors, such as the construction material and bottle shape, and choosing according to what meets your unique needs.

Bottle Neck Shape (Finish)

The neck of a bottle—i.e., the part that accommodates the closure—is of particular importance to the overall bottle design. How this component is configured—i.e., its finish—dictates the type of closure the bottle can accommodate.

When designing the bottle finish, there are a few measurements to keep in mind: 

  • Bead locating dimension: the length of the area between the top of the finish and the top of the bead
  • Bead width: the height of the bead
  • Finish start: the length of the area from the top of the finish to the bottom of the neck
  • Hole diameter: the diameter of the opening
  • Major diameter: the diameter including the threads
  • Minor diameter: the diameter not including the threads
  • Thread start: the length of the area from the top of the finish to the topmost section of the thread

With these design elements in mind, some of the commonly used neck finishes you may choose from include:

Step 2: Evaluate Potential Suppliers and Identify a Quality Partner

Choosing a bottle supplier can be challenging, as it’s not always possible to visit the locations of all potential partners and meet face-to-face with their teams. However, by acquiring the answers to the following questions, you can get a better sense of whether a company would be a good fit for your product and production needs:

  • — How long have they been in business?
  • — Do they have a fully fleshed out professional website?
  • — What are their prices?
  • — Do they carry inventory?
  • — Where are they located?
  • — What is the cost of shipping?
  • — What is their standard delivery time?
  • — Do they have a return policy?
  • — Do they offer product samples?
  • — How do they rank on non-affiliated business websites, such as BBB or Bizrate?

You will also need to determine whether the supplier you’re considering has experience supplying bottles for use in your particular industry. At WB Bottle Supply, we serve many industries, including the following:

Step 3: Look for Value-Added Services
