Why San Francisco Businesses Choose Us
Why Choose Our Zip Lock Bags
Custom Zip Lock Bags | Resealable Packaging for Food, Retail & Cannabis
Zip lock bags combine practical resealability with custom branding capability — the press-to-close zipper system that keeps products fresh between uses, combined with full-color printed surfaces that communicate brand identity and product information at retail and in the customer's home. Our custom zip lock bags are manufactured from polyethylene and co-extruded film constructions engineered for the specific product and usage application.
Zip Lock Bag Applications
- Food Storage Bags: Resealable bags for snacks, dried goods, pet treats, coffee, and specialty foods requiring repeated access
- Retail Product Bags: Printed zip lock bags for hardware items, craft supplies, cosmetic samples, and small retail products
- Cannabis and CBD: Standard and child-resistant zip lock configurations for cannabis and hemp products
- Pharmaceutical Samples: Zip lock bags for pharmaceutical sample packaging and clinical trial supplies
- Industrial and Parts: Heavy-duty zip lock bags for industrial components, hardware, and parts storage
Construction Options
Standard zip lock bags use clear LDPE (low-density polyethylene) film — flexible, food-safe, and transparent for product visibility. Frosted zip lock bags use a semi-transparent PP film for a premium matte appearance. White opaque zip lock bags provide a full print surface on a non-transparent background. Barrier zip lock bags combine polyethylene with metalized or foil lamination for moisture and oxygen-sensitive products.
Clear vs. Frosted vs. Opaque Zip Lock Bags
Film selection for zip lock bags directly affects both practical function and brand perception. Clear LDPE film is the most common — fully transparent for product visibility and identification. Frosted PP film creates a milky, semi-transparent appearance that obscures the product while suggesting premium brand positioning — popular with cosmetics samples and premium snack brands. White opaque film provides a full-surface print canvas with no product visibility — used when branding takes priority over product display, or when the product's appearance is not a positive selling attribute.
Child-Resistant Zip Lock Bags for Regulated Products
Child-resistant zip lock bags use specialized zipper mechanisms that require simultaneous pressing at specific points and sliding — a two-step process that young children cannot reliably execute but adults find straightforward. CR zip lock bags are certified to CPSC 16 CFR 1700.20 and are required for cannabis edibles, CBD gummies, pharmaceutical samples, and other regulated product categories in applicable jurisdictions. We produce CR zip lock bags in standard sizes for the cannabis and pharmaceutical industries.

Zip Lock Bags in San Francisco — FAQs
Are zip lock bags food-safe?
Yes. Our zip lock bags use food-grade LDPE film and food-safe adhesives and inks that comply with FDA 21 CFR requirements for indirect food contact. For direct food contact applications, we specify food-grade materials throughout the construction.
What is the difference between press-to-close and slide zipper?
Press-to-close zippers use interlocking plastic channels that snap together when pressed with finger pressure — the most common resealable mechanism. Slide zippers use a sliding lock mechanism that travels along the zipper track — easier to operate with one hand and more reliably sealed. Slide zippers are preferred for larger bags and for products used in situations where single-hand access is important.
Can zip lock bags be printed with my brand?
Yes. Printed zip lock bags use flexographic or digital printing on the outer film surface. White opaque bags provide the best print surface with vivid CMYK color. Clear bags are printed on the outer surface, with the print visible through the film from the inside. Frosted bags offer reduced print contrast relative to opaque bags.
What sizes are available?
We produce zip lock bags in standard sizes from 2×3 inches (small parts and sample applications) to 12×16 inches (large retail and food storage applications). Custom dimensions are available outside standard sizes. Thickness options range from 2 mil (light duty) to 6 mil (heavy duty industrial applications).
