Start choosing materials from constraints, not from preferences.

The most common question Sinh Vũ hears when consulting on packaging is: "What type of paper is the most beautiful?" or "Which material is the most luxurious?" These are the wrong questions to start with. The material is not the starting point; it is the result of three constraints you need to clarify first. Starting from aesthetic preferences, you may choose beautiful materials, but they may not be suitable, may not run well on your printing machine, and may not fit within the actual budget.

Three binding decisions on materials

Before viewing any price lists or templates, you need to answer the following three questions:

• What does the product fear: moisture, oxygen, light, impact, or lack of special protection requirements. This is a technical constraint that cannot be overlooked.
• In what context do customers hold it: holding it on a supermarket shelf, opening it at home, transporting it long-distance, or displaying it for a long time. The way it is handled determines the durability and tactile feel needed.
• Budget per unit based on your actual output: not ideal output, but the output from the first print run. Cheap materials in large batches can be very expensive in small batches.

These three answers will narrow down the list of available materials. The remaining part is when aesthetics can be discussed.

Legal constraints must be considered upfront, not added later.

If the product comes into direct contact with food, cosmetics, or pharmaceuticals, you need to confirm this before anything else. Materials in contact with food must be safe for health and not alter the smell, taste, or color of the product. This is the first bullet point requirement, according to international regulations on food contact materials (for example, EC Regulation 1935/2004 by the European Commission applicable to exports to the EU).

If you are exporting or planning to export, another question to ask is: does the target market have any regulations regarding ink, coatings, or the recyclability of packaging? Knowing this early avoids the need to redo printing after completion.

The capabilities of the printing machine, a factor often overlooked

A beautiful material on paper may not perform well on the printing machine you are working with. This is not the fault of the printer or the material, but rather information that needs to be clarified before making a decision.

• Can the printer handle that material, or do you need to switch to another printer?
• Are there any local facilities capable of performing post-print finishing (foil stamping, lamination, embossing)?
• Does the design file meet the standards for that material and printing process?

Sinh Vũ is not a printing house, but a creative director connecting with partner printing houses. Therefore, when advising on materials, Sinh Vũ always includes questions about machine capabilities and file standards, as these two aspects are interconnected.

Common errors when starting to choose materials

• Choose based on the image of another brand without knowing they have completely different product constraints.
• Skipping the step of checking the printing machine's capabilities means discovering the material won't work only at the time of printing.
• Investing in high-quality materials for untested products, only to have to change them when adjusting the product.
• Budgeting in large batches while initially printing only a small batch leads to actual costs being much higher than anticipated.

Material must meet all three criteria: protect the product, be suitable for use, and run on the printing machine. Missing any of the three means that attractive packaging is still the wrong packaging.

The viewpoint of Sinh Vũ

Every time we receive a packaging brief, Sinh Vũ starts by asking what the product fears and how the customer handles it before suggesting any materials. This is not a procedure but a way to provide informed advice instead of imposing a familiar material and forcing the product to fit.

If you are at the idea stage and do not have enough information to answer all three constraints, that is not a problem. Start with what you know, and clearly identify what is missing. The best material decision is made when the right questions have been asked, not necessarily when all answers are available from the start.
