Paper bag: choose handles, weight, and finishing

A customer carrying a branded paper bag down the street is a mobile advertisement that incurs no additional media costs. However, if the wrong paper weight, handle style, or purpose of the paper bag is chosen, the result could be a torn handle in the street, faded print colors that obscure the brand, or food leaking through the bottom of the bag. This page helps you understand what type of bag you need and what information to provide so that Sinh Vũ can create the correct file for the printer.

What is a paper bag?

A paper bag is an outer packaging made from paper, used to hold products, create branded shopping bags, or as outer packaging for gift combos. It is identified by three structural factors.

First is the bottom type. A square self-standing bottom (SOS, short for "self-opening sack") allows the bag to stand on its own when placed on a table, convenient for takeout food or display bags. A pinch bottom is flatter and neater, commonly found in gift bags and fashion bags.

Second is the handle type. Twisted handle made from paper can bear the heaviest load in the group, suitable for groceries and food. Flat handle is a flat strip of paper glued to the bag body, more economical, suitable for light to medium items. Die-cut handle has no separate handle, is the most compact but has the least load capacity.

The third factor is the paper weight, measured in grams per square meter (GSM). According to reference frameworks from suppliers, lightweight bags use about 60 to 80 GSM, medium bags 70 to 90 GSM, large bags with handles require about 100 to 120 GSM, while premium tote bags (euro tote) are 200 GSM or higher. The higher the GSM, the thicker the paper, which retains shape and supports weight better. This is a reference framework from foreign suppliers, not a strict standard from Sinh Vũ.

Regarding surface materials: brown kraft gives a rustic handcrafted feel, but a dark background can distort the printed colors, making it difficult to reproduce bright colors. Coated paper (surface-coated paper) prints colors more accurately and responds well to finishing techniques like foil stamping, embossing, and spot UV.

When to choose, when not to

A paper bag is suitable when you need a branded outer layer, not a preservation solution. The most reasonable cases include:

• Shopping bags at retail points, fashion stores, bakeries.
• Corporate gift bags for the standard tier (VIP tier usually uses rigid boxes).
• Besides the common gift combo, containing many small items inside already has its own packaging.
• Light takeaway food, dry pastries without oil, using SOS style or twisted handles depending on the load.

Cases where paper bags are not the right choice:

• Oily or watery food: paper that does not block oil or moisture will soak through and break.
• Liquid products or those that need to be sealed: paper bags without sealing mechanisms cannot replace laminated bags or stand-up pouches with zip locks.
• A heavy, absolutely luxurious feel is needed: a rigid box is still far superior.
• Heavy materials in thin, flat-handled bags: torn handles are a real risk.

Costs, time and quantity

Paper bags fall into the low to mid-range segment of paper packaging, but actual costs vary greatly depending on three factors: paper quality and weight, printing method, and level of finishing.

Regarding printing methods: offset printing is economical for large runs due to the initial setup costs. Small runs typically use digital printing, which has a higher cost per piece but does not require a plate. Premium finishing such as foil stamping, embossing, and die-cutting requires specific molds and plates, adding time and setup costs.

Regarding time: there is no specific verification number for the Vietnamese market, so Sinh Vũ does not provide a fixed weekly timeline. Qualitatively: small batches printed digitally are faster, while large batches printed offset or with complex processing take more time. You should plan early if there is a hard event deadline.

Sinh Vũ takes on the role of creative director: designing the structure of bags, surface graphics, and exporting files that meet print standards. Sinh Vũ does not commit to printing prices as printing quotes depend on the printer you choose and the specific production batch.

What does Sinh Vũ need from you to get started

To allow Sinh Vũ to advise accurately and produce standard design files from the start, you need to provide:

• Expected size and weight: What will the bag hold, and how much does it weigh? This helps Sinh Vũ determine the appropriate GSM and handle type.
• Quantity and market: How many units in the batch, retail or corporate gifts, one-time or repeat orders. This affects the recommended printing method.
• Desired level of processing: simple kraft bags or premium embossed couche with foil. If unsure, describing the brand feeling you want to create is sufficient.
• Reference budget: no need for an exact number, just need to know whether you are in the common, mid-range, or premium segment for Sinh Vũ to propose appropriately.
• Timeline: Is there a specific event or launch date to prioritize the design schedule and communicate with the printer in time?
• Compliance requirements: If the bag comes into direct contact with food, confirmation that the material meets food contact standards is needed. Sinh Vũ will note this requirement in the brief for the printer.

You can submit your request through Sinh Vũ's contact form. The more information you provide, the shorter the Q&A cycle will be, allowing Sinh Vũ to make a more realistic proposal right from the start.
