A Curious Case of Prewar Packaging

While browsing through archival footage of 1930s Manila, I stumbled upon a fleeting yet curious moment: a mother handing what appeared to be a white plastic bag, or perhaps a bundled parcel, to her son seated in a calesa. The image startled me. Plastic? In the 1930s? That couldn’t be right. I paused, rewound, and watched again. The object had the unmistakable crinkle and sheen of modern plastic. But something didn’t add up.

Driven by curiosity, I dove into a bit of impromptu research. It turns out that the ubiquitous polyethylene grocery bag, the kind we now associate with supermarkets and convenience stores, wasn’t invented until 1965, when Swedish engineer Sten Gustaf Thulin patented the design. Even then, it took another decade or so before these bags became widespread, particularly in the 1970s and 1980s. So, if plastic bags weren’t around in the 1930s, what exactly was I seeing?

One possibility is cellophane, a transparent film made from regenerated cellulose. Invented in the early 20th century and commercially available by the 1920s, cellophane was widely used by the 1930s, especially for wrapping food items. Its glossy, crinkly texture could easily resemble plastic on grainy black-and-white film, especially in fleeting shots where detail is obscured.

Alternatively, the mysterious bundle might have been wrapped in waxed paper or oiled cloth, both common materials for food packaging at the time. These materials were practical, reusable, and widely available. Glassine, a smooth, semi-translucent paper often used for baked goods and confections, is another contender. Likewise, acetate film, though more commonly associated with photography and early cinema, was also used in packaging and could appear plastic-like on camera.

In the Philippine context of the 1930s, traditional packaging materials such as banana leaves, woven palm baskets (bayong), and cloth wraps were still prevalent, especially in local markets. However, imported goods, particularly from the United States or Europe, may have introduced early synthetic or semi-synthetic packaging materials into the local scene. Given the colonial ties and the cosmopolitan nature of prewar Manila, it’s not implausible that such materials found their way into everyday life, at least among certain segments of the population.

Ultimately, the object in question may not have been plastic at all, but rather a clever illusion born of light, texture, and the limitations of early film technology. A crumpled piece of cellophane or waxed paper, caught in just the right light, could easily masquerade as a modern plastic bag to our contemporary eyes. History often hides in plain sight, waiting for us to look closer, and question the things we thought we already knew.
