Safety Sack pouches boast child-resistant zipper technology

September 13, 2017

Safety SackGrowth in flexible packaging continues, with one of the more intriguing subsegments the development of a type of packaging that a few years ago didn’t seem possible: child-resistant pouches and bags. There are now CR options applicable for medical, chemical and other markets. One report forecasts the global child-resistant packaging market at a CAGR of around 5.2% for the period 2016 to 2025.

Vendors continue to develop pouches and bags with proprietary CR features, including Dymapak (New York City), an OEM supplier of industrial safety packaging. This summer the company began accepting custom orders for Safety Sacks, a line of CR vacuum-sealable premade pouches.

“We believe Safety Sacks will revolutionize child-resistant packaging in the pharmaceuticals, cannabis, and at-home segments,” Steven Annunziato, Dymapak’s COO, tells PlasticsToday. “Our new product utilizes our patented Kid Katch zipper technology, which is fully contained within the zipper of the pouch. The key to the functionality is the counterintuitive zipper design that depends less on the strength of the user and more on their skill and experience. The unique design uses considerably less plastic than rigid containers, costs a fraction of the price of other child-resistant packaging and enables leading companies to promote their brands through full design customization.”

Kid Katch is a patented zipper technology designed to prevent child access that meets CR packaging poison prevention protocols set by the Consumer Product Safety Commission and American Society for Testing and Materials (ASTM).

“In addition to its reclosable child-resistant capabilities, Safety Sacks have an approximately one-inch header above the zipper that is tamper-evident when heat sealed,” Annunziato adds.

The premade pouches’ design offers an inherent advantage for customers.

“A primary advantage in the Safety Sack construction lies in the patent-pending child-resistant zipper mechanism which not only eliminates unsightly and bulky locking mechanisms, but also allows the product to qualify for what’s known as a range of certification,” he explains. “That means that all sizes between the smallest and largest tested are automatically certified and there is no need to apply for certification every time a different size is requested by a customer, assuming that the desired size stays within that range.”

Lab certification as a poison prevention package that meets CFR 16 1700.20 guidelines is a springboard to widespread commercialization.

“More than one million Safety Sacks were sold in our first production run that are expected to hit the market in early-October 2017,” Annunziato discloses.

The fact that customized Safety Sacks are available is also boosting customer interest, he notes. “This construction also enables us to provide customers with a broad variety of customizable options such as retail-friendly peg holes and transparent windows as well as various finishes and special materials.”

Options include a matte finish, kraft paper, various gusset styles, spot gloss and more.

Annunziato lists the major advantages of Safety Sacks versus competitive CR pouches:

  • Minimal tooling adjustments to produce;
  • Customizable to make nearly any size pouch;
  • Capability to be nitrogen-flushed and hermetically sealed;
  • They are extremely difficult for children to open—99% successful at keeping children out in tests.

“The fact that our pouch can be hermetically sealed means it can safely transport and protect contents,” Annunziato points out. “We believe this feature will enable mail-order pharmacies and nutraceutical companies to more cost effectively ship goods to customers.”

We asked Annunziato how Safety Sacks are different from the Child Guard Slider launched in late 2014 as reported by sister publication Packaging Digest.

“There several distinct differences between the Safety Sack and the Child-Guard slider, but the construction of the zipper is perhaps what separates them the most,” he responds. “Not only can the Safety Sack be manufactured on a standard pouch-making system with minimal tooling adjustments, it requires no injection molding which reduces production costs, lead-times, and transportation costs.

“Furthermore, unlike the alternatives offered by our competition, Safety Sacks contain no vulnerabilities like the widely-recognized issue of children separating the zipper to access the contents, bypassing the slider entirely.”

Flexible benefits

Annunziato also points to the overall advantages of child-resistance in a flexible format compared to traditional rigid containers.

“Like other flexible packaging options, our pouches use significantly less plastic than rigid containers,” he says. “There is an ongoing shift from rigid to flexible packaging across many industries. We believe our disruptive technology will accelerate the adoption of flexible packaging for products that require child-resistant protection.”

Safety Sacks are available as stock items in a variety of discrete sizes between 3 in. x 3 in. and 12 in. x 9 in. x 2.75 in. in either opaque white or black; custom sizes can be ordered in virtually any size in between this range in a minimum order quantity of 10,000 pouches.  

Dymapak products are available in eight countries, including more than 600 stores in the United States, and can be purchased online at For more information, email [email protected] or phone 917-210-1067 ext. 1.
