Why Choose Our Grip Seal Bags
Custom Grip Seal Bags | Reclosable Press-Lock Bags for Pharmacy, Parts & Retail
Grip seal bags — also known as press-lock bags or ZipGrip bags — use an integrated reclosable closure system where two interlocking polyethylene channels are pressed together to seal the bag opening. This simple, reliable reclosure mechanism is the dominant format for retail pharmacy packaging, parts storage, sample packaging, and any application requiring repeated access without the complexity of an external zipper mechanism.
Grip Seal Applications
- Pharmacy and Dispensing: Printed grip seal bags for pharmacy prescription dispensing — the standard format for dispensing counted tablets and capsules
- Parts and Hardware: Clear grip seal bags for retail parts display and storage in hardware, electronics, and automotive applications
- Craft and Hobby: Grip seal bags for beads, findings, seeds, stamps, and craft supply retail
- Sample Packaging: Grip seal bags for cosmetic, food, and product sample distribution
- Document and Card: Crystal clear grip seal bags for document protection, trading cards, and collectible packaging
Grip Seal Bag Specifications
Standard grip seal bags are manufactured in clear LDPE with 2 mil (standard) and 4 mil (heavy duty) thickness options. Printed grip seal bags add branding and product information using flexographic printing in 1–4 colors. Anti-static grip seal bags use LDPE blended with anti-static compounds for electronic component packaging. Colored grip seal bags in opaque LDPE are available for security and privacy applications.
Grip Seal Bags in Pharmacy Dispensing
Grip seal bags are the dominant format for retail pharmacy prescription dispensing of solid oral dosage forms — counted tablets and capsules dispensed from bulk stock into patient prescription bags. The press-lock closure allows pharmacists and pharmacy technicians to fill, label, and reseal bags efficiently on high-volume dispensing lines. Printed pharmacy dispensing bags include mandatory labeling fields (patient name, prescription number, drug name, dose, directions, prescriber, dispensing pharmacy) that comply with state pharmacy board labeling requirements.
Anti-Static Grip Seal Bags for Electronics
Standard LDPE is an insulating material that accumulates static electric charge — hazardous to electrostatically sensitive components including integrated circuits, MOSFET devices, and precision sensors that can be damaged by static discharge of a few hundred volts. Anti-static grip seal bags use LDPE blended with anti-static compounds that dissipate electrical charges before they can accumulate to damaging levels. For higher ESD protection requirements, pink anti-static bags provide charge dissipation, while shielding bags (metalized) provide full Faraday cage protection against external electrical fields.

Grip Seal Bags in Cambridge — FAQs
What is the difference between a grip seal bag and a zip lock bag?
Grip seal bags and zip lock bags use the same press-to-close interlocking channel closure mechanism — these terms are often used interchangeably. The distinction is primarily application context: 'grip seal' is common in pharmacy, laboratory, and industrial contexts; 'zip lock' is common in consumer food and retail contexts. Both use the same reclosure technology and performance characteristics.
Can grip seal bags be printed?
Yes. Printed grip seal bags use flexographic printing in 1–4 spot colors on the outer surface. Pharmacy dispensing bags include required label fields printed on the bag. Retail parts and hardware bags include product descriptions, part numbers, and brand information. Full CMYK printing is available at higher minimum quantities.
What thickness grip seal bag do I need?
2 mil LDPE is the standard for most pharmacy, sample, and light retail applications. 4 mil LDPE provides heavier gauge for hardware parts, industrial components, and applications where the bag is handled repeatedly over extended periods. 6 mil LDPE is available for heavy-duty storage and industrial applications. Thickness selection balances cost against the durability requirements of the specific application.
Are anti-static grip seal bags adequate for semiconductor packaging?
Anti-static (pink polyethylene) bags dissipate surface charge accumulation but do not provide protection against external electrostatic fields or electromagnetic interference. For semiconductor packaging requiring full ESD protection, metallized shielding bags (Faraday cage construction) are required. The appropriate bag type is determined by the component's ESD sensitivity classification (ESDS class 0, 1, 2, or 3 per JEDEC/ESD standards).
