Ziploc bags have been a household staple for decades, providing an easy and secure way to store food and keep it fresh. So, when were Ziploc bags invented? The answer lies in the early 1960s, with a company called Dow Chemical.
In the early 1950s, Dow had developed a thin, transparent plastic film for packaging goods. This material was known as Saran Wrap and quickly became popular as a way to preserve food. However, while Saran Wrap was effective at preserving certain types of foods like meats and cheeses, it wasn’t ideal for storing liquid or other moist foods.
Dow recognized this shortcoming and began exploring new ways to create leak-proof containers that could be used in households across America. These efforts led to the creation of polyethylene plastic bags which were initially marketed as sandwich bags.
But these early versions of polyethylene bags did not feature any type of sealing mechanism – you would just fold over one end of the bag several times before clasping it shut with a clothespin or rubber band. While this method worked well enough for some uses , there remained issues such as spills or decomposition which caused people using them frustration.
It wasn’t until 1968 that Edson Gould realized there might be another option beyond folding down one end multiple times. As an inventor who had previously created packaging equipment that seals products into plastics containers much more easily than earlier by automating laminating machines (a task requiring manual labor), he decided further research on creating hermetic seal designs would be worthwhile.”
To solve this issue, Dow brought in designer Doug Strobel to develop a new solution that could make their plastic bags truly air-tight and water-tight;this is how zippered storage bags came into existence.Gould presented his initial designs calling for ease-of-use,the quick snap ‘zipper’ they featured helped significantly differentiate what would become branded under S.C Johnson’s trademarked name ‘Ziploc’ from their competitors.
Released in 1968, the Ziploc bags were an instant hit with consumers looking for better ways to store food and other items. By the early 1970s, they became a staple in households across America and worldwide.
The unique zipper mechanism allowed one-handed opening and closing of these plastic bags while at the same time providing a secure seal against leaks or spills.By the late 1990s, small modification have been made to reduce both material cost while also improving the effectiveness of sealing mechanisms.The additions included slider zippers which allowed re-use as well adjustments to be made more easily.As new materials like heavy-duty freezer-grade polyethylene were implemented,ZIpLoc products steadily evolved and continue to by popular among consumers today.
In conclusion, Ziplock bags played a transformative role in consumer goods space due not just its convenience but also its effectiveness—both of which originated from Gould’s hermetic seal was perfected through Strobel’s designs.Today it remains as integral part modern that help make everyday tasks such as packing lunch easier,in addition being used extensively for shipping personal belongings safely & securely.A humble creation that has transcended beyond basic household item–just goes on show how innovation can arise any aspect life!
Ziploc bags are a staple in most households, allowing us to store food and other items easily and conveniently. However, the history of these little zippered bags goes back a few decades. It was in the early 1960s that Dow Chemical took on the challenge of creating leak-proof containers for household use.
The story begins with Saran Wrap, a thin transparent plastic film developed by Dow in the early 1950s. This revolutionary product quickly became popular as it allowed people to preserve their food effectively. However, Saran wrap wasn’t perfect when it came to storing liquid or moist foods – which led Dow Chemical to start exploring new materials.
In its quest for better storage solutions, Dow developed polyethylene plastic bags; originally marketed as sandwich bags, they still lacked an effective sealing mechanism. One had to fold over one end several times before clasping it shut with either clothespin or rubber band – not an ideal solution by any means.
Then Gould intervened-Edson Gould was a prolific inventor who recognized that there might be another way altogether beyond folding down one end of bag.He suggested comprehensive research towards hermetic seal design,Gould began designing packaging equipment to automate laminating machines.Edson’s strategic alliance along with Doug Strobel managed to solve this issue successfully.
Strobel’s new design featured unique zippers that made Ziploc bags truly air-tight and water-tight.The quick snap action helped differentiate them from competitors significantly
Initially released under S.C Johnson’s trademarked name ‘Ziploc’, these innovative zippered storage bags quickly rose in popularity becoming a must-have item in every household throughout America.By using just one hand,you could open/close while at same time providing secured security against spills.Years later,Different variations emerged incorporating slider zippers making reuse possible such stipulations contributed towards decreasing material cost among consumers.
Over time innovations occurred including designer Otto Rohwedder’s freezer-grade polyethylene implementation have contributed towards Ziploc’s continued success.The bags continue to be a reliable storage solution for both consumers and industries alike.
Ziplocs are now available in an array of sizes, colors, patterns, and some even have built-in handles for easy carrying. So next time you use it perhaps consider how far these little bags have come over the years — from humble beginnings to transforming our life with convenience that we all take for granted today!
