Some sources say that plastic and other wrappings actually speed up spoilage because they hold in air, but for the most part packaging slows food spoilage. The functions of packaging include acting as a barrier against microbial, physical and chemical protection.
Physical: - e.g. cardboard stops bruising of fruits, therefore preventing enzymic degradation of the flesh.
Microbial: Perhaps the most important aspect of food preservation. Packaging such as plastic or metal can prevent the entry and growth of microorganisms that break down food components and cause off smells and bad textures. For example, plastic wrapping over a half-eaten steak prevents entry of microbes that break down proteins and fats.
Chemical: Light and oxygen can causes damage to food by increasing the incidence of rancidity (e.g. autooxidation [fat breakdown]) and vitamin degradation (for example riboflavin in milk breaks down it the presence of sunlight). This is why most milk bottles are opaque and gas-impermeable, which means Oxygen can't come in. Another example is cellulose film wrapping of bread, which prevents staling by stopping sntry of oxygen.

What year did Louis Pasteur conduct experiments on the spoilage of food?
Louis Pasteur conducted his experiments on the spoilage of food in the 1860s. His groundbreaking work demonstrated that microorganisms cause food spoilage and spoilage can be prevented through processes such as pasteurization. This research significantly advanced the field of microbiology and food preservation.
How do enzymes cause food spoilage?
There are enzymes that speed up the chemical reaction components in food which leads to spoilage. Enzymes can be slowed down so that food spoilage doesn't occur as quickly by keeping food in cold temperatures.
