Custom Packaging Bags Ordering Mistakes: 7 Pitfalls to Avoid

Ordering custom packaging bags without a structured process can result in unexpected costs, missed launch dates, and packaging that underperforms in the supply chain or on the retail shelf. Whether you are sourcing custom printed mylar bags, stand up pouches, or flat bottom bags, the most common custom packaging bags ordering mistakes often begin long before production starts—in the specification, quotation, and proofing phases.

This guide outlines seven procurement pitfalls that experienced packaging buyers learn to avoid, along with a practical checklist you can use to improve your next RFQ.

Why Ordering Mistakes in Custom Packaging Bags Hurt Your Bottom Line

Custom flexible packaging is not a commodity purchase. Each project involves interdependent decisions about bag format, material structure, size, printing method, functional features, and compliance documentation. When one variable is overlooked or assumed, the cost can cascade through the entire project.

Common consequences of custom bag procurement errors include:

• Budget overruns caused by reprints, material changes, or expedited shipping to meet a launch date.
• Production delays when specifications are clarified or corrected after the initial quote.
• Product quality issues such as poor barrier performance, incorrect bag dimensions, or color mismatches that affect shelf presentation.
• Compliance risks when food-contact material requirements are assumed rather than verified.

The following sections break down each mistake and explain what buyers can do to prevent it. If you are preparing a new packaging project, you can also request a quote for custom packaging bags and our team will help you review your specifications.

Mistake #1: Focusing Solely on the Lowest Unit Price

Price comparison is a natural part of procurement, but selecting a supplier based on the lowest quoted unit price—without confirming that each quote is based on identical specifications—is one of the most expensive packaging order mistakes to avoid.

A quote for a custom pouch is only meaningful when it is based on a full specification set:

When two quotes differ substantially, the cause is often incomplete specification sharing—not a genuine price advantage. A proper RFQ process compares like-for-like quotes built on the same material, size, feature, and print requirements. Our products overview can help you identify the right bag format before requesting quotations.

Mistake #2: Overlooking Material Structure and Barrier Performance

Material structure is the foundation of packaging performance. It determines how well a bag protects its contents from moisture, oxygen, light, and physical damage. Ignoring or simplifying this decision is one of the most critical ordering custom pouch pitfalls.

Different products require different barrier levels. A snack product with a short shelf life may perform well in a PET/PE structure, while coffee beans or tea leaves often need a foil or metallized layer for aroma protection and moisture resistance.

Material recommendations should be confirmed against your product type, shelf-life target, storage environment, and destination market. Providing this information early in the quotation process helps suppliers recommend an appropriate structure. If you are exploring resealable zipper options or other features, the material structure must also be compatible with those additions.

Mistake #3: Neglecting Food-Contact Material Compliance

For food, beverage, pet food, and health product brands, compliance with food-contact material regulations is not a detail to confirm after production—it is a specification requirement that should be addressed during supplier evaluation and material selection.

Regulatory frameworks differ by market:

• United States: FDA food-contact regulations apply to packaging materials in direct contact with food.
• European Union: EC Regulation 10/2011 governs plastic materials and articles intended for food contact.
• Additional standards: REACH, RoHS, and national standards may apply depending on product category and destination market.

Key questions to ask your packaging supplier:

• What food-contact test reports or certificates are available for the proposed material structure?
• Do the reports cover the specific layers and adhesives used in the laminate?
• Are the compliance documents applicable to the product type and target market you are shipping to?
• Can the supplier provide documentation before you approve the material?

At Custom Pouch Pack, available compliance documents—including FDA food-contact test reports, EU EC 10/2011 reports, REACH test reports, and RoHS certificates—can be reviewed according to project requirements. However, material suitability and compliance scope should always be confirmed against your specific product, packaging format, and market regulations. You can review available compliance documents by sharing your project details with our team.

Mistake #4: Providing Incomplete or Incorrect Artwork

Artwork errors are a frequent source of delays in custom packaging projects. Issues discovered during the proofing stage often require multiple revision cycles, pushing back the entire production timeline.

Common artwork problems include:

• Wrong file format: Printers typically require vector files (AI, EPS, or high-resolution PDF) rather than low-resolution JPEGs or PNGs.
• Missing bleed: Artwork should extend beyond the final trim line to prevent white edges after cutting.
• Unconverted fonts: Fonts should be converted to outlines or embedded to avoid substitution errors.
• Incorrect color mode: Pantone (PMS) spot colors are recommended for brand color consistency; CMYK process printing may produce different results.
• Missing or misplaced elements: Barcode position, nutritional panels, regulatory text, and window/valve locations should be verified against the bag template before submission.

A thorough artwork review before submitting files for proofing can prevent costly reprints and production delays. When preparing your custom printed packaging, ask your supplier for a dieline template and artwork specification sheet early in the process.

Mistake #5: Skipping the Sample or Proofing Stage

In an effort to reduce lead time or save on sample costs, some buyers approve production based solely on a digital proof. This is a significant risk. Digital proofs cannot replicate the tactile qualities, exact color rendering on a physical substrate, zipper functionality, seal strength, or material thickness of the final product.

Physical samples allow buyers to verify:

• Bag dimensions and capacity with actual product fill
• Material feel, stiffness, and drape
• Print color accuracy against brand guidelines
• Zipper, tear notch, and valve functionality
• Seal integrity and opening experience
• Shelf display appearance and retail readiness

The cost and time investment in a sample is minimal compared to the financial impact of a production run that does not meet expectations. Sample options—such as digital prints, material samples, or production-quality samples—should be discussed based on your project stage, artwork readiness, and material structure. Skipping this step is one of the most preventable custom packaging bags ordering mistakes a buyer can make.

Mistake #6: Ignoring Functional Features and User Experience

Functional features like zippers, tear notches, hang holes, clear windows, and degassing valves are not decorative additions—they directly affect product freshness, consumer convenience, and retail display performance. Selecting the wrong features, or omitting necessary ones, is a common oversight in custom bag procurement errors.

Each feature has implications for material compatibility, cost, and production complexity. For example, a clear window changes the barrier properties of that section of the bag, and a degassing valve requires a specific installation process. Discuss feature requirements early in the specification phase to ensure the final bag design supports both your product protection needs and your customer’s experience. Explore stand up pouches with feature options to understand what is available.

Mistake #7: Vague or Changing Specifications Mid-Project

Custom packaging production follows a sequential workflow: specification → quotation → artwork review → proofing → production. When specifications change after the quotation stage—such as altering the bag size, switching material structure, adding a zipper, or adjusting quantity—the project often requires a revised quote, new material confirmation, and potentially a new sample.

A detailed RFQ is the foundation of a successful custom packaging project. Incomplete or evolving requirements are one of the most common sources of delays and cost overruns.

To avoid this pitfall, provide all key details in your initial inquiry:

• Product type and form (powder, liquid, granules, solid)
• Target fill weight or volume
• Desired bag type and approximate dimensions
• Material or barrier requirements
• Printing method, color count, and finish preference
• Functional features (zipper, valve, window, tear notch)
• Order quantity or quantity range
• Target market and any known compliance requirements
• Expected delivery timeline

Providing this information upfront enables your supplier to prepare an accurate quotation and reduces the likelihood of specification-related delays. You can contact our team with your specifications to start the quotation process.
