The COVID-19 pandemic began toward the end of 2019 and the ensuing restrictions, such as social distancing, led to the rapid growth of the delivery industry and online shopping, thereby significantly impacting consumption behavior. Consequently, many industries and companies have invested significant resources in online marketing. In addition to changes in social trends, consumption patterns have shifted from physical to online shopping, further highlighting the significance of visual stimulation. Visualization is a significant tool to attract attention, especially for digital (online) displays. Therefore, whether the type and design of the packaging will affect the attitude and attention of consumers from the screen’s perspective needs to be studied.

Of late, reusable packaging, which indicates environmental awareness, has become a significant social trend. Many start-up companies, responding to the lifestyle changes caused by the pandemic, have redesigned and launched their services—for example, providing reusable containers—and cooperate with multiple business chains to simultaneously respond to the current living situation as well as meet the requirements of environmental protection. Additionally, countries worldwide are committed to reducing single-use plastic (SUP) packaging use to construct a circular economy [1]. However, most previous studies have focused on food or delivering packages ^[2][3][4][5][2,3,4,5] neglecting the daily supplies.

Recently, with the rise of minimalism, the packaging and logos of many brands have been simplified, dramatically changing from the earlier physical packaging marketing. Packaging design is an important but needs to be better understood as a visual merchandising tool [6]. Favier et al. [7] mentioned that package design complexity can impact the purchase intention and decision-making of consumers who prefer the simple over the complex. Therefore, many brands have simplified their brand logos to improve brand logo recognition. Many big companies, such as Google, Apple, Nike, Starbucks, Burger King, and Pepsi have simplified their brand logos in form and color. The color of the package label significantly impacts preference; for example, a black logo is more attractive than a colored one [8]. However, the effect of a monotone logo on consumers’ cognition of consumption attitudes remains to be identified.

Given the significance of packaging and logos, the type of form element that can attract consumers has become a crucial research topic. Attention and attraction signify the first stage of the attitude toward further consumption behavior and visual communication to understand the product or service [9], which is a cognitive stimulation [10] and has a crucial effect on further purchase attitude [11].

2. Pandemic-Induced Changes in Consumption

The COVID-19 pandemic has significantly impacted the human society and reshaped consumers’ spending habits ^[12][19]. The delivery industry has grown in response to social distancing requirements, and traditional business models and activities have become more digital-based ^[13][20]. In addition to digital technology support, the contactless delivery business has dominated the retail and logistics industry in the post-pandemic era ^[14][21]. Some studies have questioned whether consumer behavior patterns will return to physical purchase patterns after the epidemic ^[15][16][22,23]. However, although most countries have lifted COVID-19 restrictions, consumers seem satisfied with the online experience ^[17][24]. However, the use of SUP in containers and packaging, mainly to prevent infection, has led to a massive generation of garbage ^[18][19][25,26]. Consequently, disease prevention and environmental protection have become a protracted tug of war, upending the efforts to reduce plastic use ^[20][21][27,28]. Today, disease prevention is relatively more important, but in the bargain, the pace of environmental protection and focus on sustainability have significantly reduced ^[22][23][24][29,30,31].

3. Visual Communication

Previous research has shown that visual communication plays a major role in designing packaging and logos to attract consumers ^{[7][25][26][27][28][29][30][31][32][33]}[7,32,33,34,35,36,37,38,39,40]. Visual communication is universal and can transcend language boundaries because of greater inclusivity and unity ^[34][41]. It provides lucid and attractive information that facilitates cognitive and emotional comprehension ^[34][35][41,42]. Silayoi and Speece ^[27][34] proposed that visual packaging is a significant factor affecting consumption decisions for low-involvement goods, which constitute a product category that is routinely purchased ^[25][32]. The struggle for finite attention makes it more important for marketers to understand what grabs and keeps consumers’ attention ^[36][43].

4. Environmental Awareness through Packaging

As consumers worldwide become more aware of environmental issues, product packaging increasingly emphasizes sustainability ^[37][44]. Plastic is one of the biggest sources of pollution, and unlike other materials, it is indecomposable. According to Greenpeace, an independent campaigning organization, only 2.4 million tons out of the 51 million tons of plastic waste generated in U.S. households in 2021 was recycled; it also claimed that most plastic waste is not recyclable ^[38][45]. Several countries have imposed regulations prohibiting SUP. However, such measures can only temporarily address the problem and may even impede consumer perception of eco-circulation in the long term ^[18][25]. A better mitigation or resolution option is the Closed-Loop Supply Chain (CLSC)—an efficient concept to retrieve a product or reuse it or its parts to restore its value ^[39][46] and reduce the need for raw materials ^[18][25]. As the COVID-19 pandemic gradually recedes and life returns to the pre-pandemic routine, this unresolved problem needs to be addressed. It necessitates multi-party coordination involving multiple stakeholders, including the government, people, and corporations ^[40][47], especially since packaging is a major source of non-biodegradable waste that harms the environment ^{[41][42][43][44]}[48,49,50,51]. Although previous research has focused on package reduction and recycling, it has largely ignored packaging reuse ^[45][52], which can limit the material used, reduce waste, conserve resources, and have a positive environmental impact ^[46][53]. Therefore, the Ellen MacArthur Foundation (EMF) ^[47][54] proposed four reuse models and generalized behaviors expected of consumers in two dimensions: refill and return. Many companies have designed strategies to implement reusable RPS (Reusable Packaging Systems) for fast-moving consumer goods (FMCG) around the principle mentioned above and have found that consumers are more willing to use packaging that is not deformable and is easy to clean ^[45][52]. The form of the package can also guide or deliver the meaning of the product to consumers ^[48][55]. Clement et al. ^[49][56] hypothesized that products with characteristic shapes and high contrast are more likely to attract consumers’ initial visual attention. However, they found that fewer features are more capable of attracting consumers at first glance. Once a consumer forms cognition about a product or packaging after a positive perception has been generated, it transforms into an attitude and affects his/her decision-making ^[28][50][35,57]. Wang et al. ^[51][58] also proposed the “Simple = Authentic” theory, indicating that a simplified package does not significantly affect recognition of a familiar brand. However, it remains to be proven whether visual observation alone can arouse consumers’ environmental awareness and promote purchase intention.

5. Logo Simplification

A logo is a graphic design for consumers to identify a company or its products, regardless of whether it contains its name ^[52][59]. It is one of the most powerful brand elements ^[53][60] because it can deliver brand image, attract attention, increase brand awareness, differentiate, and elicit emotional responses ^{[52][54][55][56][57][58][59]}[59,61,62,63,64,65,66]. A logo is an identification and signature of a company, service, or product ^[60][67] and arouses consumers’ expectations ^[52][61][59,68]. It not only has higher stimulation and recognizability compared to text ^[62][69] but also promotes the brand’s value and philosophy ^[63][70]. With the progress of information teleportation, interaction, and communication showing diversity, the visual aspect of marketing has become the preferred medium of product and social communication ^[64][71]. Research shows that a novel logo has a positive impact on the social distancing situation ^[65][72]. The logo significantly impacts the brand image ^[66][67][73,74] and enhances the purchase intention of consumers ^[68][75]. Chen et al. ^[69][76] stated that simplification is the main element in designing logos. A brand can improve its recognition and achieve stronger impressions through simplified images ^[70][77]; the lower visual complexity is judged more favorably and increases consumers’ willingness to purchase ^[71][72][78,79]. Furthermore, the logo’s attractiveness is enhanced by a simple form and smooth style—a trend confirmed by recent packaging designs ^[73][74][75][80,81,82].
