Introduction:
First custom packaging bag order, got scammed 30,000 yuan.
This was the exact words of a customer who does nut roasting last week. He found a supplier on 1688 with the lowest quote, but ended up receiving bags with poor sealing, severe color differences in printing, and even 20 days late than agreed. It coincided with the Mid-Autumn Festival stocking season, directly affecting his shipment.
His experience is not an isolated case. On the path of custom soft packaging,Information AsymmetryIt’s the biggest hidden purchasing cost for medium and small food enterprises. In this guide, we’ll fully break down the complete process of custom packaging, common pitfalls, and selection logic, helping you avoid unnecessary detours and reduce costs.
I. The Correct Way to Customize Packaging
Many purchasing managers’ first reaction is “just give me a price” — but if you haven’t even clarified the bag type and material you need, the price quoted by the supplier is basically of no reference value.
Custom Soft PackagingFive Core Decision PointsWe recommend following this order:
Step 1: Determine the bag type
| Bag Type | Applicable Scenarios | Typical Products |
|---|---|---|
| Three-side sealed bag | Basic bag type, suitable for low weight and low cost products | Seasoning Powder, Coffee Sample Pack, Shampoo Sample |
| Back-seal bag / middle-seal bag | No edge sealing on the front, large printing area, suitable for brand display | Candies, chocolates, cookies |
| Eight-Side Sealed Bag | Strong three-dimensional appearance, excellent shelf display effect, with a bottom support panel | Coffee Beans, Nuts, Tea Leaves |
| Stand-up bag with zipper | Re-sealable closure, excellent consumer experience | Pet treats, fruit snacks, frozen foods |
| Accordion pouch (side-sealed/middle-sealed) | Large capacity, stable standing | Rice, cat litter, bulk nuts |
| Flat bag | Lowest cost, suitable for inner packaging or bulk scenarios | Bread inner bags, bulk weighing bags |
Selection Recommendations: If your product needs to compete face-to-face with competitors on supermarket shelves, prioritize the following:Eight-Side Sealed BagorStand-up bag with zipperTheir natural three-dimensional shape makes them more noticeable to consumers than flat bags. For e-commerce channels, the capacity advantage and large printing area of accordion bags are more suitable for online visual display.
Step 2: Select Material Structure
Material isn’t necessarily better the more expensive it is, but rather whether it meets the specific requirements of the product.The better the match, the better.The key is to look at three indicators:
- Barrier Properties: What are your products afraid of? Products prone to oxidation, such as nuts and coffee, require an aluminum foil or metallized layer. Products susceptible to moisture, such as cookies and expanded snacks, require high moisture barrier materials.
- Tensile strength: Is the bag “standing” or “lying”? An eight-seal bag requires a higher stiffness material to maintain a three-dimensional shape.
- Heat Sealing Property: The PE inner layer is the most common heat-seal layer, affecting the seal strength and filling efficiency.
Common Composite Structures Reference:
| Product Type | Recommended Structure | Cause |
|---|---|---|
| Nuts / Roasted Nuts | BOPP/Aluminum-Coated PET/PE | Anti-oxidation, moisture-proof, cost-effective |
| Coffee Beans | PET/Aluminum Foil/PE | High barrier with one-way vent valve |
| Frozen Food | PA/PE | Low-temperature resistant, puncture-resistant |
| Expanded Food Products | BOPP/VMCPP | Lightweight, moisture-proof, low cost |
| Tea | Kraft paper/Aluminum foil/PE | Lightproof, moisture-proof, natural texture |
Step 3: Determine Specifications and Dimensions
This step may seem simple, but60% of beginners make mistakes here.Common mistakes include:
- Calculate bag dimensions based on product volume directly (ignoring expansion space after filling)
- The automation filling equipment hasn’t considered the tolerance requirements for bag dimensions.
- The actual capacity and flat dimensions of a stand-up bag differ significantly after the bottom is expanded.
Correct procedure: First provide product samples to the packaging factory for testing.Capacity TestRecommended size is determined by our technical staff based on your filling method and target net content. Never estimate it yourself.
Step 4: Determine Printing Process
Soft packaging printing is mainly divided into two types:
- Offset Printing (Traditional): High color saturation, suitable for bulk orders (usually starting from 10,000 meters), with plate-making fees ranging from hundreds to thousands of yuan.
- Digital Printing (Emerging): No plate required, low minimum order (as low as 1,000 meters), fast delivery, but higher per-unit cost, suitable for small quantities, multiple versions, or market testing.
Selection Recommendations: If the product is mature with stable annual demand, flexo printing is more cost-effective overall. For new product launches with many SKUs but small order quantities, digital printing offers greater flexibility—avoiding the need to invest several ten-thousands of yuan in plate costs for a single new flavor.
Step 5: Confirm Additional Features
Modern flexible packaging is increasingly incorporating functional accessories, but each addition increases cost and process complexity:
- Zipper (self-sealing strip): Most commonly used, suitable for products that need to be opened and closed repeatedly
- One-way exhaust valve: Coffee bean packaging standard, expelling carbon dioxide while blocking external oxygen
- Easy-tear notch (laser cut / serrated cut): Enhance consumer unboxing experience
- Hanging hole (airplane hole/circular hole): Suitable for display on supermarket shelves
- Clear Window: Show real product samples to increase purchasing confidence
Please provide the Chinese text you would like translated. Only include necessary functions; avoid unnecessary features. Every extra function adds to the cost, and that cost will ultimately be passed on to your product.
II. Full Process Timeline for Custom Packaging
From “I want to produce a batch of packaging” to “goods arrive at the factory,” the complete soft packaging customization cycle typically takes15-25 working daysThe following is a standard timeline:
| Phase | Job Description | Estimated time |
|---|---|---|
| 1. Requirement Communication | Confirm product type, bag type, capacity, budget, and delivery time | 1-2 days |
| 2. Solution Confirmation | Material structure selection, dimension recommendations, and printing process determination | 2-3 days |
| 3. Sample Design | Layout design (provided by customer or packaging factory), digital proof confirmation | 3-5 days |
| 4. Plate Making | Offset Plate Making (Skip this step for digital printing) | 3-5 days |
| 5. Print Lamination | Printing, Lamination, Calendering | 5-7 days |
| 6. Cutting and Bag Making | Cut into rolls or made into finished bags | 2-3 days |
| 7. Quality Inspection and Shipment | Appearance inspection, dimension measurement, edge sealing strength test, quantity verification | 1-2 days |
| 8. Logistics and Delivery | Point-to-point logistics delivered to the specified address | 2-5 days |
Special Notice: If you are targeting seasonal periods (Mid-Autumn Festival, Spring Festival, 618, Double 11), we recommend placing orders at least 30 days in advance.35-40 daysInitiate packaging procurement. During peak season, the capacity of plate factories and printing factories is tight, leading to potential delays in delivery. Additionally,The contract must specify the liability for late delivery.This is the only means you have to ensure suppliers deliver on time.
Three. The Top 5 Pitfalls in Packaging Procurement
Pitfall 1: Focusing only on unit price without considering total cost
Many buyers only look at “how much per bag,” but overlook:
- Defective rate (the defective rate of cheap products may be as high as 5%, making them actually more expensive in the long run)
- Filling efficiency (bags with uneven seams frequently jam on automatic filling machines, affecting production capacity)
- After-sales cost (customer complaints and returns caused by leaking bags)
Correct pricing method: Sample bag filling test → calculate overall loss → compare actual usage cost. Don’t be misled by “a lower price by one jiao.”
Pitfall 2: Producing large orders without confirming the samples
The colors on the design draft may differ significantly from the actual printed colors. The color appearance of the same ink can vary depending on the material used. Ordering a large production run without confirming with physical samples carries a very high risk.
Must do: Request suppliers to providePre-press proofing (not digital proofing)After checking the actual product for color, material feel, edge finishing, and zipper smoothness, we will sign the bulk order contract only after being fully satisfied with all aspects.
Pitfall 3: Ignoring Storage Conditions
Composite packaging bags are sensitive to high temperatures, humidity, and direct sunlight. Some customers order six months’ worth of products at once, but due to lack of temperature and humidity control in the warehouse, the bags turn yellow and become brittle after three months. Especially for bags with aluminum foil layers, improper storage can lead to oxidation of the aluminum layer.
Recommendations: Place orders in batches according to actual consumption speed, with each order’s inventory controlled within 2-3 months’ usage. If bulk stock is necessary, ensure the warehouse temperature and humidity meet standards (recommended temperature 15-30°C, humidity 40-60%).
Pitfall 4: Letting the printing factory “look at the design”
“Master, just design it in this style” — this is the most dangerous sentence. Print factory designers may not understand your brand positioning and target audience, so what they design might look good but be inappropriate.
Correct procedure: Provide at least the brand logo (vector file), brand color values (CMYK), product selling points copy, and required label information (ingredients, nutritional facts, production license number, etc.). Allow the designer to work within a clear framework.
Pitfall 5: Ignoring Regulatory Requirements
Label information on food packaging is subject to strict regulatory requirements. Many new brands focus only on “looking good,” only to discover missing critical information after printing, resulting in the need to discard all the printed materials.
Make sure to check: Are all the mandatory labeling contents required by GB 7718 (General Rules for Prepackaged Food Labels) complete? Is the format of the nutrition facts table correct? Is the font height of the net content compliant with the standard?
Four. A Complete Procurement Decision Checklist
We recommend that each packaging procurement supervisor confirms the following checklist item by item before placing an order:
- Bag type has been confirmed (three-side sealed / middle sealed / eight-side sealed / stand-up bag / accordion bag / flat bag)
- ✅ Material structure has been confirmed (including barrier layer solution)
- Dimensions have been verified through capacity testing.
- ✅ Printing process has been selected (gravure printing/digital printing)
- Additional features have been evaluated for necessity (zipper, vent valve, tear notch, hanging hole, window)
- Samples have been physically confirmed (not digital drafts)
- The layout includes complete regulatory information
- The contract clearly specifies the delivery schedule and penalty clauses for delays.
- ✅ Storage conditions meet the storage requirements
- Minimum Order Quantity (MOQ) matches your specific requirements
