This is the most popular type of box, glued on the sides with adhesive. It is a low-cost box used as a minimum sales unit in various industries.

"I want a versatile box that is user-friendly and blends well with any product at a low cost." — This ideal is embodied in the caramel box (sack box). Among various packaging options, it boasts an overwhelming popularity as the most common type, with its greatest appeal lying in its excellent cost performance, which directly relates to ease of implementation. The simple design, with one side glued, exemplifies functional beauty stripped of excess. While keeping manufacturing costs down, it continues to support the minimum sales units across various industries. Its usability is outstanding, featuring an intuitive structure that simply requires inserting the top and bottom. This significantly enhances the efficiency of product packing and supports smooth shipping. Particularly as individual packaging for relatively lightweight products such as cosmetics, pharmaceuticals, and daily goods, its capabilities are well established. Trusted to the extent that it is often said, "If in doubt, choose this," it is the standard in the packaging world. Would you like to present your products in a more accessible and smarter way?

Applications/Examples of results

The reasons why "Muchacha-en," a company developing a natural cultivation citrus business in Ehime Prefecture, has continued to place orders with Kaypack since the launch of its cosmetics brand "yaetoco" in 2012 are mainly threefold. Firstly, the overwhelming quality of the finished products. It achieves a texture that elevates customer excitement, suitable for high-priced natural cosmetics. The durability is also high, preventing deterioration from rubbing or color fading during transport, which ensures that the brand image is not compromised in stores. Secondly, the flexibility and speed of response. Utilizing its integrated system, the company has a proven track record of saving the day with short lead times and high-quality responses even during material shortages due to rapid sales increases. Thirdly, the accurate proposal capabilities as a professional. Rather than just printing according to data, they proactively point out and suggest improvements from a professional perspective, including the reproduction of fine text, barcode reading accuracy, and material selection that matches the brand's atmosphere (such as a matte high-end feel). In this way, a production system with minimal waste and high reliability has led to the evaluation of Muchacha-en as an "irreplaceable partner" that shapes their commitment.

[Package Production Case Study / Vol. 1] The reason why Kurekosu Co., Ltd. has continued to order organic cosmetics packaging for over 20 years.

  • NEW
  • Product news

When buying new cosmetics, while the bottle design is important, what catches the eye first is definitely the "box." When faced with a selection of many cosmetics and unsure of which to choose, it often comes down to "package buying," akin to buying based on the cover. This time, we asked our long-time partner, the cosmetics manufacturer Kurekos Co., Ltd., why they continue to create packages with Kaypack. 【I can no longer remember when we started our dealings with Kaypack】 We began our dealings with Mr. Kita (Kaypack) over 20 years ago, so long ago that I can hardly remember the beginning. In the early days, we relied on another packaging company. However, since starting our relationship with Mr. Kita (Kaypack), we have entrusted the majority of our packaging production to them. There is a mutual understanding cultivated over our long relationship, and the sense of security that comes from knowing everything is understood makes it easier to request work. There is a level of stability that allows us to build trust.
