Guide to Selecting Barrier Film for High-Fat Indonesian Coffee Brands to Preserve Flavor and Aroma Quality

High-fat coffee products, such as ground coffee mixed with vegetable fat or creamy ready-to-brew coffee, are highly susceptible to oxidation caused by exposure to oxygen, light, and moisture. The right barrier film will block the entry of these elements, thereby preventing the development of rancid flavors and keeping the coffee aroma fresh until the expiration date. This material is also suitable for products distributed to high-humidity regions across various parts of Indonesia.

When selecting materials, manufacturers can consider multilayer films with combinations of materials such as polyethylene, aluminum foil, or metalized film according to protection requirements. For products that need extra protection against light and oxygen, films with an aluminum layer are a commonly used option, while metalized film can serve as a lighter-weight alternative. Film thickness also needs to be adjusted to the packaging method, whether it is vacuum packaging, nitrogen gas filling, or convenient sachet packaging.

In terms of cost, films with higher protection levels generally have higher production prices than standard packaging films. Manufacturers are advised to balance product protection needs with available budgets, especially for the middle to lower market segments. In addition, ordering materials in quantities matching production capacity can help reduce storage costs and the risk of material damage before use.

Finally, pay attention to the production and delivery time of materials from suppliers, especially for films with special specifications that require additional printing and lamination processes. Manufacturers should place orders well before the mass production schedule to anticipate delays that could disrupt the supply chain. Conducting packaging trials with product samples is also an important step to ensure the barrier film's performance meets the desired quality standards.
