During the design of easy-tear zip-lock bags, carelessness often results in an untidy appearance. For instance, in many cases, even the patterns and text are cut off, or the seams are poorly joined. In numerous instances, color issues stem from design flaws; therefore, when reviewing a product’s design draft, we should pay close attention to these minor details.

During the design of easy-tear zip-lock bags, carelessness often results in an untidy appearance. For instance, in many cases, even the patterns and text are cut off, or the seams are poorly joined. In numerous instances, color issues stem from design flaws. Therefore, when reviewing a product’s design draft, it’s important to pay attention to these subtle details. Below, we’ll outline the key considerations for designing easy-tear zip-lock bags:

1: The design layout of the easy-tear zip-lock bag should maintain a 1 cm margin from the cut edge to prevent accidental cutting during trimming. Text must be converted into curves or outlines. Manufacturers of easy-tear zip-lock bags recommend avoiding system‑generated fonts; when such fonts are used, white nodes may appear at stroke intersections. After converting text to curves, carefully check for any gaps or overlaps between words or lines. Do not apply register fills to black text.

2: The product’s design color should not be based on the colors displayed on a screen or printed by a printer. Customers should refer to the CMYK color percentages to determine color fill. Additionally, due to variations in materials, ink types, printing pressure, and other factors, CMYK color charts produced by different manufacturers may differ even within the same color swatch.

3: With the same tear‑open zipper bag design but different printing, a color difference of within 10% is normal (as ink‑volume control varies with each batch). For main‑machine printing and finishing, if old files are available, to prevent excessive color variation, we can only refer to the digital color swatches provided by our company.

4: The design sketch for the easy-tear zip-lock bag does not show the cross-shaped mark or the cut line. Two invisible guideline boxes can be used as the production dimensions of 92 mm × 56 mm and the bleed lines; after cutting, the final size will be 90 mm × 54 mm. If you require custom dimensions, please specify them in your order and when uploading the file.

5: The color value of the easy-tear zipper bag, whether in its coloring or substrate, is designed to be less than 10% to prevent rendering issues during printing.

Easy-tear zip-lock bags are typically made from polyethylene and polypropylene. Almost all such products are manufactured using synthetic resins. Resins are the primary and indispensable component of plastic packaging, serving as an adhesive that binds the plastic structure into a cohesive whole. Although various additives can be incorporated to modify the properties of many plastic bags, the resin remains the fundamental factor determining the type of plastic and its suitability for specific applications. Food‑grade bag materials: There are two main types of materials used for food foil bags—standard packaging and those suitable for high‑temperature cooking. Standard packaging materials include PE, NY, AL, and PE, while materials designed for high‑temperature cooking comprise PET, NY, AL, and CPP.

Our company’s easy-tear zip-lock bags comply with national food‑packaging standards, are environmentally friendly and made from eco‑friendly materials; they can be custom‑made, freely spray‑coated, and are suitable for both high and low temperatures. They provide excellent thermal insulation, come with a quality guarantee, and are widely applicable—helping to preserve aroma, freshness, quality, taste, and color.
