A B2B Sourcing Guide

Finding the right supplier for PET cans can be daunting. The market is flooded with manufacturers, trading companies, and middlemen. If you pick the wrong partner, you risk leaking cans, poor clarity, or shipping delays. Here is a checklist for B2B buyers to ensure you source high-quality PET cans.
🔍 1. Virgin Material vs. Recycled Mix
Always ask the supplier about the raw material.
- Good: 100% Virgin PET resin (offers the best clarity and strength).
- Good: Certified rPET (sustainable, but may have a slight tint).
- Bad: Unregulated recycled scrap. This results in "cloudy" or yellowing plastic and weak walls. Ensure your supplier provides FDA or EU food safety certifications for their resin.
⚙️ 2. The Neck Finish and Sealing Compatibility
This is the most technical part. Not all cans fit all lids.
Standard Size: The most common neck size is "202" (roughly 52mm diameter). Ensure your supplier's can is calibrated for standard 202 SOT (Stay-On Tab) or EOE (Easy Open End) aluminum lids.
Seamer Match: Ask the supplier for the exact dimensional drawing of the "flange." Send this to your sealing machine manufacturer to confirm compatibility before ordering 50,000 units.
💪 3. Wall Thickness and Top Load Strength
Ask for the "gram weight" of the can. A can that is too light is cheaper but will buckle when you stack pallets on top of it.
- Soft Drinks: Require thicker walls to withstand internal pressure.
- Still Drinks: Require structural ribs or nitrogen dosing to stay firm. A reputable supplier will ask you what you are filling before selling you the can.
📦 4. MOQ and Lead Times
Factories often prefer massive orders. If you are a startup, look for suppliers who keep "stock molds" inventory. This allows you to buy 5,000 or 10,000 units instantly. If you need a custom shape, be prepared for a 4-6 week lead time for mold creation plus production time.
Sourcing PET cans is a partnership. Look for a supplier who asks technical questions about your filling process and sealing equipment, rather than one who just gives you a price list.
Frequently Asked Questions
❓ What is the main advantage of using 100% Virgin PET material?
Virgin PET provides the highest level of clarity, ensuring your product looks fresh. It also offers superior structural strength and complies strictly with international food safety standards (FDA/EU).
❓ How do I know if the PET cans will fit my current sealing machine?
You should request a technical drawing of the can's flange and neck finish. We recommend sharing these dimensions with your equipment manufacturer to confirm compatibility with your seamer's chuck and rollers.
❓ Can these PET cans be used for carbonated beverages?
Yes, but carbonated drinks require specific wall thickness and base designs to handle internal pressure. Always specify your drink type so the correct "gram weight" can can be provided.
❓ What is the standard lead time for a custom mold?
Custom shapes usually require 4 to 6 weeks for mold development and testing, followed by the standard production lead time depending on the order volume.
❓ Are the aluminum Easy Open Ends (EOE) included with the cans?
Usually, cans and lids are quoted separately but can be shipped together. It is essential to ensure you are sourcing the standard 202 size lids for most common beverage applications.
❓ Is there a Minimum Order Quantity (MOQ) for stock items?
For standard shapes kept in stock, MOQs can be as low as 5,000 to 10,000 units, making it accessible for startups and small-batch production.
